Question 45

Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number.

59 : 14 :: 61 : 7 :: 37 : ?

Solution

In each set, the digit sum of the first number will form the second number.

59 : 14 ==> 59 ==> 5+9 = 14

61 : 7 ==> 61 ==> 6+1 = 7

37 : ? ==> 37 ==> 3+7 = 10

So 10 will come in place of the question mark.
