The digit 7 appears 5 times: 7192747378179.
This is untimed educational practice for one cognitive skill. It is not a clinical, diagnostic, employment, or professionally recognized assessment, and it does not produce an IQ score or credential.
The digit 7 appears 5 times: 7192747378179.
12, 18, 24, and 36 are all multiples of 6; 29 is not.
The vowels are e, a, o, u, e, i, six in total.
The sequence increases by 3 each step, so the missing number is 15.
The digits '1,1' and '5,5' are each adjacent and identical, 2 pairs total.
45 + 55 = 100. The others sum to 101, 101, and 99 respectively.
Scanning only the first letter of each word, four begin with B: banana, berry, bread, and basket.
Compare the tens digit first: 98 and 99 beat the 80s, and 99 beats 98 on the units digit.
Ticking off each letter in turn (b, a, n, a, n, a) the letter 'a' appears three times.
A number is even when its last digit is 0, 2, 4, 6, or 8: here 8, 12, and 6 qualify, making three.
Move through the string one character at a time and tally each 'x': o-x-k-x-v-e-x-n-x-o gives four.
Counting only the squares while ignoring the other shapes gives four: positions 1, 3, 6, and 8.
Only B, D, and F are upper case, three capitals in total.
Filtering out the letters leaves the digits 7, 2, 9, and 1, four in total.
Scanning for vowels only, the string contains o, e, and i, three vowels.
Tally each letter as you scan: p appears three times, q twice, and r and s once each.
Fixing on triangles only, they sit at positions 2, 5, and 8, three in total.
Only R and L are capitals, so the remaining six characters (t, e, z, p, m, s) are lower case.
Check each word for a 't' followed directly by an 'h': only moth and bath contain the pair.
With only two similar characters to separate, tally the 'o's in one pass: six of the nine characters are 'o'.
Add the tens first: 17 + 20 = 37, then the units: 37 + 6 = 43.
Subtract in two easy steps: 62 − 20 = 42, then 42 − 7 = 35.
8 × 7 = 56; instant recall of the times tables is one of the biggest speed gains available.
Round 38 up to 40 for an easy sum, 45 + 40 = 85, then take the 2 back off: 83.
Use 10 × 6 = 60 and subtract one 6: 60 − 6 = 54.
Subtract 40 for a round number, 74 − 40 = 34, then add back the 2 you over-subtracted: 36.
Halve three times: 120 → 60 → 30 → 15, because dividing by 8 is halving thrice.
Pair numbers that make round totals: 13 + 28 = 41, and 41 + 9 lands neatly on 50.
Halve the parts separately: half of 70 is 35, half of 6 is 3, and 35 + 3 = 38.
Four 25s make 100: the same fact that makes four 25p coins a pound is worth keeping on instant recall.
Check letters first, then digits in order. The near-misses transpose the H and T, swap the final digits, or shuffle the 4s.
Only one pair repeats its string exactly; the others transpose the last digits (7791), swap the letters (ZM), or alter a middle digit (7119).
Three codes read PLQ-880, while the odd one out swaps the letter Q for the visually similar letter O to read PLO-880.
Read the street name letter by letter and the number digit by digit: the near-misses reverse 27, add a stray p, or change the 7 to a 1.
The spelling 'harbour' appears in the first and third positions; 'harbor' drops the u and 'arbour' drops the h, so neither is a repeat.
TK-9906 and TK-9096 differ in their middle digits, 90 versus 09, while every other pair repeats its string exactly.
Compare digit positions one at a time, then the letter: the near-misses transpose 82, swap Q for O, or move the 4.
Check each word in turn: the traps change Gray to Grey, add an extra e to Whitfield, or spell out the ampersand.
The first and third codes match exactly; 2281-DV reverses the letters and 2218-VD transposes the middle digits.
Scan each code for a repeat: 4535 contains the digit 5 twice, while the other codes use four different digits.
Substitute one symbol at a time in the order shown: ● is 2, ▲ is 1, ■ is 3, giving 213.
Each letter maps to the letter the same distance from the far end: D is 4th from the start, and 4th from the end is W.
Decode digit by digit in order: 3 is D, 4 is O, 4 is O again, 1 is R, spelling DOOR.
Apply the shift to every letter, not just some: C moves to D, A moves to B, and T moves to U.
Convert every symbol before adding, and note the repeated ◆: 4 + 7 + 2 + 4 = 17.
All four options use the same letters, so the order is everything: 2-4-6-8 decodes strictly as N, E, S, T.
Step every letter back once: D to C, O to N, and G to F.
Encode in the order the letters appear: R gives ▲, P gives ◆, Q gives ●. Watch for the option that swaps the last two.
Convert each number in sequence: 6 is F, 1 is A, 3 is C, 5 is E, FACE.
B is 2 and each E is 5, so the total is 2 + 5 + 5 = 12.
Line the decimals up place by place: 0.405 has 4 tenths like 0.45, but its hundredths digit is 0 against 5, so it is smaller.
Compare each gap from 500 rather than the numbers themselves: 32, 29, 7, and 10. The smallest gap is 7.
Convert to decimals for a quick comparison: 2/3 ≈ 0.67, 3/4 = 0.75, and 4/5 = 0.8, so 4/5 is largest.
Work both products before comparing: 7 × 8 = 56 beats 9 × 6 = 54.
Test both conditions on each number: 48 is even but too small, 57 is large enough but odd, and 45 fails both, only 62 passes both.
Compare digit by digit after the decimal point: 3.51, 3.6, and 3.55 exceed 3.5, while 3.499 falls just short.
With negative numbers the larger the digit, the colder the value: −7° sits furthest below zero.
The pounds match, so compare pence: 09 < 19 < 90 puts £9.19 in the middle.
0.25 is a quarter: 1 divided by 4. The others convert to 0.4, roughly 0.33, and 0.3.
Test each candidate against both divisors: 36 = 4 × 9 and 6 × 6, while 30 fails on 4, 40 fails on 6, and 27 fails on both.
Name the category of each word as you scan: plum, pear, and mango are fruits, while kale is a leafy vegetable.
Only the first character matters for this rule: E is a vowel, while T, B, and M are not.
Sort by what each unit measures: litres measure volume, metres length, grams mass, only minutes measure time.
Check only the last digit of each number: 12, 30, and 8 are even, so three numbers go to Box A.
Group by meaning before choosing: whisper, murmur, and mutter all describe quiet speech, while shouting is loud.
Compare each amount against the £100 threshold and watch the boundary case: £99.99 is still under it, but £102.40 is over.
Classify each animal as you read: otters, badgers, and hares are mammals, while the gecko is a lizard, a reptile.
Sort each word into colour or not-colour as you go: crimson, teal, and indigo are colours; violin and ladder are objects.
Scan each word for two identical letters side by side: only 'hammer' has one, the double m.
Test both rules on each number: 24 passes both, 31 is over 20 but odd, 18 is even but too small, only 15 is both too small and odd.
Each term adds 4 to the one before, so 16 + 4 = 20.
Check the gap between neighbours first: each step subtracts 9, so 54 − 9 = 45.
The sequence skips one letter each time (B, skip C, D, skip E…), so after H comes J.
Each term doubles the previous one, and 80 fits both neighbours: 40 × 2 = 80 and 80 × 2 = 160.
The gaps themselves grow by one each step (+1, +2, +3, +4), so the next gap is +5, giving 17.
The three-symbol block ● ▲ ▲ cycles, and the seventh symbol starts a new block, so the eighth is the block's second symbol, ▲.
These are the square numbers 1², 2², 3², 4², 5², the next is 6² = 36.
The jumps widen by one letter each time (+2, +3, +4), so the next jump of +5 lands on O.
Each term halves the previous one, so 8 ÷ 2 = 4.
Read the alternating positions as two strands: a constant 10 and the odd numbers 3, 5, 7, the odd strand continues with 9.
Hold the intermediate total before applying the second step: 14 + 19 = 33, then 33 − 6 = 27.
Doubling 17 gives 34, and 34 + 5 = 39.
Retrieve the fact first, then compute: 7 days × 6 = 42, and 42 − 2 = 40.
'Operation' contains the vowels o, e, a, i, o, five in total, and 5 × 3 = 15.
Work each sum, then classify it: 8 and 10 are even, while both 13s are odd, two even results.
Three subtractions of 8 remove 24 in total, so 50 − 24 = 26, stopping early at 42 or 34 is the common slip.
Compute both before comparing: 15% of 200 is 30, while 20% of 140 is 28.
6 × 9 = 54, and swapping its digits gives 45. The unreversed 54 is the trap to step past.
Treat each digit separately and add: 4 + 7 + 8 = 19.
'Speed' has 5 letters; 5 squared is 25, and 25 − 5 = 20.
Apply both tests to every number: 45, 61, and 73 pass, while 37 and 39 are odd but not large enough.
First isolate the digits (7, 4, 9, 1, 6), then keep only the odd ones: 7, 9, and 1.
Tally both letters in a single pass: X appears 6 times and O appears 4 times, a margin of 2.
Sum each code and compare with 10: the totals are 10, 9, 10, 11, and 10, so three codes qualify.
Check only the first letter of each word and ignore s sounds inside words: Six, sleek, swans, swam, south, and stone make six.
Filter in stages: over 30 leaves 32, 47, 56, 63; keeping the evens then leaves just 32 and 56.
Score each entry against both rules separately: 7Q34 and CD57 each break only one rule, while 9K33 starts with a digit and ends with an odd digit.
Walk the string and keep a digit only when the very next character is a letter: 3 before f, 2 before k, and 1 before m give 3 + 2 + 1 = 6.
Compare only the minutes and watch for transposed digits: three times end in :25, while 09:52 reverses those digits to :52.
Take the chain one link at a time: 'rapid' has 5 letters, doubled is 10; 'audio' has 4 vowels (a, u, i, o), giving 14; and 14 − 4 = 10.
