Its '4' and '8' are swapped relative to the other four, which all read XJ48Q2. attention-concentration-s01-q02 Read the reference and each copy in the same order, one character at a time. The copy reading TR5280 has the 8 and the 2 the other way round; everything else matches. attention-concentration-s01-q03 Three entries read Ashborne. The remaining one, Ashbourne, adds a u after the b-o, which is easy to miss because both spellings look plausible. attention-concentration-s01-q04 Both entries read HGX-407 for their first seven characters. The reference then ends 19 while the copy ends 91, so the disagreement is confined to the last two digits. attention-concentration-q3 Only pair A is identical; B, C, and D each have transposed or swapped digits. attention-concentration-s01-q06 Compare only the middle block, since the prefix and suffix are the same throughout. The exception reads 88123 where the rest read 88213, with the 2 and the 1 exchanged. attention-concentration-s01-q07 The entry reading ID0-105L uses the digit zero where the others use the letter O. Checking look-alike characters (O and 0, I and 1, S and 5) separately is the reliable way to catch this. attention-concentration-s01-q08 The entry reading DN14 6OP uses the letter O where the others use Q. Every other character in the four postcodes agrees, so the tail of the code is the only place worth checking twice. attention-concentration-s01-q09 Line the strings up and check each of the eight positions in turn: F becomes E and Q becomes O, while the other six positions agree. That gives two differences. attention-concentration-s01-q10 Checking the reference block by block rules out the rest: one swaps 2 and 0 to give 3201, one reverses the letters to JA, and one ends with a lower-case l instead of the digit 1. attention-concentration-s02-q01 Move left to right and tally only the squares: they sit in the second, fourth, sixth, eighth and ninth places, giving five in all. attention-concentration-q4 ▲ appears 4 times in the sequence. attention-concentration-s02-q03 Scan for one target letter only and ignore everything else. T appears three times across the row, so the other letters can be passed over without being read. attention-concentration-s02-q04 Adjacent pairs of the same symbol are where miscounts creep in. Counting each circle separately gives six, including the two pairs that sit side by side. attention-concentration-s02-q05 When a question asks what is not there, it is quicker to count the other symbol directly: there are four diamonds among the ten symbols. attention-concentration-s02-q06 Tally only the fours as you pass along the string; they appear four times. Keeping a finger or cursor on your place stops you rereading a digit you have already counted. attention-concentration-s02-q07 Here the target is a property rather than a particular letter, so read for shape and size only. Five of the ten letters are capitals. attention-concentration-s02-q08 Count the two targets separately and add them at the end: three triangles plus two squares makes five. Trying to hold one combined running total is where errors usually appear. attention-concentration-s02-q09 Slide a two-digit window along the string and check each overlapping pair. The pair 3 7 appears four times; a 7 followed by a 3 does not count, because the order is reversed. attention-concentration-s02-q10 Start at the second symbol and look only at what sits directly to its left. Five symbols follow a circle, and the very first symbol cannot qualify because nothing precedes it. attention-concentration-q6 "Receive" is the correct spelling. attention-concentration-s03-q02 One sentence reads "that the the invoice". Doubled small words slip past easily because the eye predicts the phrase instead of reading it, so short function words repay a second look. attention-concentration-s03-q03 The correct spelling doubles both consonants, cc and mm, and keeps an o before the d. Checking each doubled pair in turn settles which version is right. attention-concentration-s03-q04 One sentence reads "sign register" with no article between the two words. The other differences here are wording changes rather than omissions, so the sentences still read as complete. attention-concentration-s03-q05 Check the three details separately: the order number, the event and the date. Only one statement keeps 4482, pairs dispatch with 12 March, and changes nothing else. attention-concentration-s03-q06 Both the badges and the office belong to the managers, so both slots need the possessive their. There marks a place, and they're is only ever short for they are. attention-concentration-s03-q07 The title reading Senior Date Analyst changes one letter inside a familiar word. Reading job titles and headings letter by letter catches these, because we normally skim them. attention-concentration-s03-q08 One sentence reads "be against checked", with the two words the wrong way round. The others are all grammatical, even though they differ in what is being compared with what. attention-concentration-s03-q09 The instruction attaches a different action to each copy, so keep the two paired as you read: top copy with signing, bottom copy with returning unsigned. Swapping the pair is the usual slip. attention-concentration-s03-q10 The word except removes one named group from the requirement, and that group is the part-time cleaners. Full-time cleaners remain inside all staff, so they still have to attend. attention-concentration-s04-q01 Four values exceed 30: 34, 41, 55 and 37. The value 30 itself does not qualify, because the rule asks for numbers greater than 30 rather than 30 or more. attention-concentration-q5 27, 45, and 63 are odd, three numbers in total. attention-concentration-s04-q03 Test each word separately rather than scanning the list as a block: table, chair, lamp and mat contain an a, and the other three do not. attention-concentration-s04-q04 Divide each value by 4 in turn: 16, 28, 36 and 44 divide exactly, giving four multiples. Being even is not enough, which is what rules out 22, 30 and 50. attention-concentration-s04-q05 Look only at the first and last letter of each word and ignore the middle: level, radar and sees each match at both ends, giving three. attention-concentration-q2 Counting every 'e'/'E' across the sentence gives a total of 12. attention-concentration-s04-q07 Both conditions have to hold at once, so check each number twice: 22, 36 and 48 pass on both counts. The value 20 is even but not greater than 20, and 14 fails the size test as well. attention-concentration-s04-q08 Tally the row letter by letter first: B appears three times, and K, M and R each appear twice, so four different letters repeat. Only T appears once. attention-concentration-s04-q09 Only the two ends of each code matter, so read the first and last characters and skip the middle. A123, D908, F450, G612 and H33 satisfy both ends, giving five. attention-concentration-s04-q10 Apply the rules in order: the odd values are 15, 21, 33, 45, 57 and 9, and removing the multiples of 5 takes out 15 and 45. That leaves four numbers. attention-concentration-s05-q01 Search on the time first and let the activity names go by unread. Only the 19:00 book club matches, and it is held in Room 2. attention-concentration-s05-q02 Take the digits strictly left to right, letting each letter pass without being read: 4, then 9, then 2, then 7. Keeping the original order is what separates the answer from the near misses. attention-concentration-s05-q03 Reading the letters in the order they appear gives H, A, N, D. The distractors keep the same four letters but disturb their order, so the sequence has to be held as you scan. attention-concentration-s05-q04 Use the capitals as the filter and let the lower-case words fall away: RAPID, TRAIN, NORTH, MARKET. The alternatives each pull in a lower-case word or reorder the four. attention-concentration-s05-q05 Only Priya's order counts, so Marcus's coffee and the soup price are there to be ignored. Two teas at £2 plus one cake at £4 comes to £8. attention-concentration-s05-q06 Let the brackets, rather than the letters, guide your eye along the line. Four letters are bracketed, and the unbracketed ones need not be read at all. attention-concentration-s05-q07 A whole word has a space or punctuation mark on both sides, which rules out settings, reset and sunset. That leaves four genuine uses of the word on its own. attention-concentration-s05-q08 The instruction rules out anything beyond the surname, so a title, a first name or an initial all count as extra. The entry giving Okonkwo on its own is the only one that adds nothing. attention-concentration-s05-q09 The bracketed text names what to avoid, not what to do, so the instruction is to use number 14 and to arrive after 2pm. Reading the brackets as the instruction is exactly the trap being set. attention-concentration-s05-q10 Two filters apply at once: the train must go to Leeds and must actually run. The 09:15 is cancelled and the other 09:45 service goes to York, so the earliest remaining option is the 09:45 to Leeds. attention-concentration-s06-q01 Count the letters from the start of the word: H is first, A second and R third. Counting from the wrong end or starting at zero are the two common slips. attention-concentration-s06-q02 Carry out the selection before the arithmetic: the even numbers are 6, 12 and 18, and adding those three gives 36. attention-concentration-s06-q03 Work the steps in the order given: 7 plus 5 is 12, and doubling 12 gives 24. Doubling first and then adding would give 19 instead. attention-concentration-s06-q04 The list holds seven items, and the instruction removes exactly two of them, leaving five. Counting the whole list first makes the subtraction easy to check. attention-concentration-s06-q05 Read the word from its last letter back to its first: Y, A, D, S, E, U, T. The near misses reverse most of the word but transpose a pair in the middle. attention-concentration-s06-q06 The format fixes three things at once: day before month, two digits for each, and four digits for the year. Only one entry satisfies all three without reordering the day and month. attention-concentration-s06-q07 A total of exactly 50 is not more than 50, so it falls into the second condition, which covers 50 or less. Boundary values are worth reading twice for this reason. attention-concentration-s06-q08 Take one step at a time and carry the running value forward: 10 minus 3 is 7, times 4 is 28, minus 2 is 26. Stopping a step early gives 28, and multiplying before subtracting gives 38. attention-concentration-s06-q09 Apply the main rule first and the exception second: A123, C77K, D908, F450 and G612 begin with a letter, and C77K is then removed for ending with one. Four codes survive. attention-concentration-s06-q10 Notebook is the longest word at eight letters, and eight is even, so the second half of the instruction applies and the answer is doubled to 16. Stopping before the condition gives 8, and measuring lantern instead gives 14. attention-concentration-s07-q01 Tally each symbol type separately and subtract at the end: six circles against four squares leaves a difference of two. attention-concentration-s07-q02 Total each team before comparing them: Team A reaches 10 and Team B reaches 11, so Team B is ahead by a single point. attention-concentration-s07-q03 Hold two values as you scan and update either one only when a number beats it: the highest is 47 and the lowest is 9, so the difference is 38. attention-concentration-s07-q04 There are four vowels (A, E, O and I) against three appearances of T, so the vowels lead by one. Keeping the two tallies physically separate stops them merging. attention-concentration-s07-q05 Follow each lift to the end before comparing: Lift 1 finishes on floor 4 and Lift 2 on floor 8, so Lift 2 ends higher. attention-concentration-s07-q06 Four stars contribute 8 and three diamonds take away 3, leaving 5. Counting each symbol type first and applying the weights afterwards is less error-prone than adjusting a total symbol by symbol. attention-concentration-s07-q07 Take the shorter list and test each of its entries against the longer one: 1 is missing from Y, while 3 and 6 appear in both. attention-concentration-s07-q08 One value has to be stored while the other is still being built up: the first number is 6 and there are 7 entries, so the product is 42. attention-concentration-s07-q09 Clerk 1 takes customers 2, 4, 6, 8 and 10, so everyone left over sits in an odd position. Noting where the alternation starts is what settles which half each clerk gets. attention-concentration-s07-q10 The two letters directly after an X are skipped, which removes one R and one B from the tally. That leaves three Rs against two Bs, so red leads by one. attention-concentration-s08-q01 The first three become 7, 8 and 9 and the last three become 7, 8 and 9 as well, so each group totals 24 and the whole comes to 48. Applying the first rule to all six numbers would give 51. attention-concentration-s08-q02 The results are 8, 16, 14 and 19, which add to 57. Saying the current rule to yourself before each number keeps the alternation from drifting. attention-concentration-s08-q03 Two vowels appear before the slash and two consonants after it, giving a total of 4. Carrying the first rule past the slash would count the wrong letters in the second half. attention-concentration-s08-q04 The original numbers total 90, and the adjustments are plus 1 four times and minus 1 twice, a net gain of 2. Working with the change rather than recalculating every entry keeps the switch clear. attention-concentration-s08-q05 Row 1 opens with a letter, so its three letters are counted; row 2 opens with a digit, so its three digits are counted. The two counts add to 6. attention-concentration-s08-q06 Two circles qualify before the switch and three squares qualify after it, giving five in all. Symbols that do not match the rule in force at the time are simply passed over. attention-concentration-s08-q07 Working left to right gives 3 plus 4 is 7, times 2 is 14, plus 5 is 19. The instruction overrides the usual convention of doing multiplication first, which would give 16 plus a leftover step. attention-concentration-s08-q08 Desk and lamp have four letters each, so they contribute d and l; chair and stool have five, so they contribute r and l. Checking the length before choosing the rule is the whole task. attention-concentration-s08-q09 Each stretch contributes two items (two numbers, then two letters, then two numbers) for a total of 6. The rule has to be reinstated at the third stretch, which is where the count often slips. attention-concentration-s08-q10 The odd positions give 10, 12 and 9, and the even positions give 5, 6 and 7, so the six results add to 49. Tracking the position as well as the value is what makes this a switching task. attention-concentration-s09-q01 Reading is close to automatic, so the written word arrives before the colour does. Naming the ink means answering green, since that is the colour the word BLUE is printed in. attention-concentration-s09-q02 The question is about how each item is written, not what it is worth. Two items appear as digits, and their values play no part in the answer. attention-concentration-s09-q03 The note settles the conflict by naming which cue has authority, and here that is the arrow. Since the arrow points right, the word on the label can be set aside. attention-concentration-s09-q04 Three words are printed in capitals. The meanings are deliberately number names so that they pull towards arithmetic, but the question only concerns the printing. attention-concentration-s09-q05 Meaning and type size both point the wrong way here, so count the letters instead: LONG has four and SHORT has five. attention-concentration-s09-q06 Find the entry by its opening word, then report only what the brackets hold. The entry beginning with square carries triangle in brackets. attention-concentration-s09-q07 The note gives the words authority over the arrow, so the wording on the sign stands in full: north, three miles away. The physical direction of the post is the cue to suppress. attention-concentration-s09-q08 Count letters rather than think about colours: three, six, four and four respectively, so the six-letter word wins. BLUE and GREY tie, which is why neither can be the answer. attention-concentration-s09-q09 Order the values first (61, 55, 48, 39), and then step one place down from the top. The largest, 61, is named in the instruction precisely because it is the tempting answer. attention-concentration-s09-q10 The third instruction resolves the clash by giving priority to the later of the two, which is the one asking for the total. Adding 7, 12 and 5 gives 24. attention-concentration-s10-q01 The digit 5 appears six times, including one place where two of them sit side by side. Adjacent repeats are the usual reason a long string is undercounted by one. attention-concentration-s10-q02 Counting what does qualify is easier than counting what does not: four triangles plus three diamonds makes seven symbols outside the two named types. attention-concentration-s10-q03 Each code has to pass two tests, so check both before moving on: AB12, 9P8, 3T and MN4 mix the two character types, giving four. The rest are all letters or all digits. attention-concentration-s10-q04 Update one running figure at each step rather than saving the arithmetic to the end: 26, 22, 31, 19, 22 and finally 15. attention-concentration-s10-q05 Five letters follow a Q, and one of those is itself a Q, which still counts because the rule is about position rather than identity. The final Q has a letter after it, so it qualifies too. attention-concentration-s10-q06 Select on the colour and ignore the item type: 12, 15 and 9 are the blue entries, and they add to 36. attention-concentration-s10-q07 Five words carry a doubled pair: tt in letter, ll in ballot, rr in mirror, mm in summer and tt in kettle. Reading each word letter by letter is what makes the pairs visible. attention-concentration-s10-q08 Six numbers are odd and six are even, so neither group leads. A list that alternates in places encourages a guess, which is why both tallies are worth completing. attention-concentration-s10-q09 Five entries open with a vowel and three close with an s, so the result is 5 minus 3, or 2. Some entries fall into both counts, and that is allowed because the two tallies are made independently. attention-concentration-s10-q10 Filter on size first, which removes 18 and 20, then drop the multiples of 3: 27, 45, 33 and 24. The five survivors are 22, 31, 26, 41 and 29. Source: https://learn.novusstreamsolutions.com/cognitive-skills/attention-concentration
