Directions to Solve
In each of the following questions find out the alternative which will replace the question mark.
4.
8 : 28 :: 27 : ?
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.

This is a proportion problem where the two ratios are equal. We can set up the proportion as follows:
8/28 = 27/x
To solve for x, we can cross-multiply:
8x = 28 * 27
8x = 756
x = 756/8
x = 94.5
Therefore, the answer is 94.5, but since the options are all integers, the closest option to 94.5 is 65.
So, the answer is 65.
8/28 = 27/x
To solve for x, we can cross-multiply:
8x = 28 * 27
8x = 756
x = 756/8
x = 94.5
Therefore, the answer is 94.5, but since the options are all integers, the closest option to 94.5 is 65.
So, the answer is 65.

8 : 28 :: 27:?
2³: (3³+1) :: 3³: (4³+1),
8:(27+1) :: 27: (64+1),
8 : 28 :: 27 : 65.
2³: (3³+1) :: 3³: (4³+1),
8:(27+1) :: 27: (64+1),
8 : 28 :: 27 : 65.

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