Question: 8 : 28 :: 27 : ?
[A].

28

[B].

8

[C].

64

[D].

65

Answer: Option D

Explanation:

First number = 8 and the sum of the digits of the second number is 2 + 8 = 10.

Thus the difference of the first number and the sum of the digits of second number is 10 – 8 = 2.

Similarly, the sum of the digits of third number is 2 + 7 = 9.

Hence the sum of digits of fourth number should be 2 more than 9 i.e. 11

Hence, fourth number is 65.
