Question

If 14 * 64 = 39, 25 * 37 = 31 and 9 * 17 = 13, then what will be 52 * 46?

A.

49

B.

51

C.

42

D.

38

Correct option is A

LOGIC = (first number divide by 2 ) + (second number divided by 2)
If 14 * 64 = 39,
(14 divided by 2) + (64 divided by 2) = 7 + 32 = 39
25 * 37 = 31
(25 divided by 2) + (37 divided by 2) = 12.5 + 18.5 = 31
9 * 17 = 13,
(9 divided by 2) + (17 divided by 2) = 4.5 + 8.5 = 13
similarly for 52 * 46
(52 divided by 2) + (46 divided by 2) = 26 + 23 = 49
