Directions to Solve
In each of the following questions find out the alternative which will replace the question mark.

4.
8 : 28 :: 27 : ?
28
8
64
65
Answer: Option
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.

2^3=8 :3^3=27+1=28,
Similarly,
3^3=27: 4^3=64+1=65.
