number-puzzles-22483.png

The arrangement is as follows :
In fig. (A), (3² + 6²) – (2² + 4²) = (9 + 36) – (4 + 16)
= 45 – 20 = 25
In fig. (B), (7² + 11²) – (8² + 6²) = (49 + 121) – (64 + 36)
= 170 – 100 = 70
In fig. (C), let the missing number be x.
Then, (1² + 4²) – (5² + x²) = –12

number-puzzles-22946.png

Putting A = 1, B = 2, C = 3, D = 4 ... X = 24, Y = 25, Z = 26,
We have F + P = 6 + 16 = 22 : G + N = 7 + 14 = 21
: J + E = 10 + 5 = 15.
Since K = 11, so value corresponding to missing letter
= (27 – 11) = 16
So, the missing letter is the 16th letter of the English alphabet, which is P.

number-puzzles-22934.png

We have (56 + 15) – (22 + 8)
= 41, (46 + 9) – (10 + 6) = 39
So, missing number = (34 + 11) – (14 + 6) = 25.

Which character when placed at the sign of interrogation shall complete the chart ?

number-puzzles-22922.png

We have : 3 × 5 + 1 = 16 ,
16 × 5 + 1 = 81, 81 × 5 + 1 + 1 = 406.
So , missing number = 406
406 × 5 + 1 = 2031.

number-puzzles-22897.pngnumber-puzzles-22891.png

The sum of the two numbers in the upper part is 7 times the number in the lower part.
So, missing number = (89 + 16) + 7 = 15.

Which character when placed at the sign of interrogation shall complete the chart ?

number-puzzles-22885.png

We have : (3 × 4 × 2 × 5) ÷ 10 = 12 ;
(6 × 2 × 3 × 5) ÷ 10 = 18.
So, missing number = (2 × 2 × 9 × 5) ÷ 10 = 18

Which character when placed at the sign of interrogation shall complete the chart ?

number-puzzles-22879.pngnumber-puzzles-22873.png

We have : (5 x 3) + (6 x 8) = 63, (2 x 7) + (3 x 9) = 41
So, missing number = (6 x 7) + (8 x 5)
= (42 + 40) = 82.

Which character when placed at the sign of interrogation shall complete the chart ?

number-puzzles-22867.png

We have : number-puzzles-23088.png + number-puzzles-23080.png + number-puzzles-23074.png + number-puzzles-23068.png = 26 ;
number-puzzles-23062.png+ number-puzzles-23074.png + number-puzzles-23050.png + number-puzzles-23043.png = 21
So, missing number
= number-puzzles-23074.png + number-puzzles-23031.png + number-puzzles-23088.png + number-puzzles-23080.png
= (5 + 12 + 6 + 8) = 31

Which character when placed at the sign of interrogation shall complete the chart ?

number-puzzles-22861.pngnumber-puzzles-22855.png

We have (15 – 5) (2 + 6) = 80, (9 – 4) (7 + 6) = 65

Which character when placed at the sign of interrogation shall complete the chart ?

number-puzzles-22849.pngnumber-puzzles-22843.png

The number inside the circle is obtained by multiplying the sum of the upper number, the lower number and the number corresponding to the position of the letter in the english alphabet, by the number on the right and then subtracting the number on the left from the product.
Thus we have (2 + C + 5) x 3 – 4 = (2 + 3 + 5) x 3 – 4 = 26 ; (4 + H + 4) x 5 – 10 = (4 + 8 + 4) x 5 – 10 = 70.
Let the missing number be x.
Then (8 + J + 6) × x – 6 = 90
⇒ (8 + 10 + 6) × x = 96 ⇒ x = 4.

Which character when placed at the sign of interrogation shall complete the chart ?

number-puzzles-22830.png

The letter in the second column is three steps behind that in the first column, and the letter in the third column is four steps behind that in the second column. So, the missing letter in the first row will be three steps behind Z, which is W. The missing letter in the second row will be four steps behind O, which is K. The missing letter in the third row will be three steps ahead of G, which is J.

Which character when placed at the sign of interrogation shall complete the chart ?

number-puzzles-22824.png

The letters in the first row follow the sequence + 5, + 7.
The letters in the second row follow the sequence + 6, + 8.
In the third row, the first letter G moves 7 steps forward to give the second letter N. Clearly, the missing letter will be 9 steps ahead of N i.e., W.

Which character when placed at the sign of interrogation shall complete the chart ?

number-puzzles-22818.png

Putting A = 1, B = 2, C = 3, ......., M = 13, ....., X = 24,
Y = 25, Z = 26, we have :
In the first column, F – A = 6 – 1 = 5 = E.
In the second column, W – J = 23 – 10 = 13 = M.
∴ In the third column, missing letter
= O – K = 15 – 11 = 4 = D.

Consecutive letters occupy alternate positions in each row.

Which character when placed at the sign of interrogation shall complete the chart ?

number-puzzles-22806.png

The letters in the first row form a series C, D, E (a series of consecutive letters). The letters in the second row form a series I, K, M (a series of alternate letters). Similarly, the letters in the third row will form the series D, G, J (a series in which each letter is three steps ahead of the previous one). So, the missing letter is G. Also, the number in the second column is equal to the product of the numbers in the first and third columns.
So, missing number is (4 × 7) i.e., 28.
Thus, the answer is 28G.

Which character when placed at the sign of interrogation shall complete the chart ?

number-puzzles-22799.png

In each row, out of the letters A, B and C, each of these must appear one. Also, in each column. The product of first and third numbers is equal to the second numbers so, the missing number will be (2 x 4) i.e., 8 and the missing letter will be C. Thus, the answer is 8C.

Which character when placed at the sign of interrogation shall complete the chart?

number-puzzles-22928.png

We have: 4 × 2 – 1 = 7,
7 × 2 + 1 = 15,
15 × 2 – 1 = 29,
29 × 2 + 1 = 59,
59 × 2 – 1 = 117,
117 × 2 + 1 = 235.
So missing number
= 235 × 2 – 1 = 469.
