9 : 727 :: 8 : 510 :: 4 : ?
Option 1: 58
Option 2: 60
Option 3: 67
Option 4: 62
Correct Answer: 62
Solution :
Given:
9 : 727 :: 8 : 510 :: 4 : ?
Subtract 2 from the cube of the first number, to get the second number in each number pair –
Like, 9 : 727→9
3
– 2 = 729 – 2 = 727
And, 8 : 510→8
3
– 2 = 512 – 2 = 510
Similarly, 4 : ?→4
3
– 2 = 64 – 2 = 62
So, the required number is 62. Hence, the fourth option is correct.
