Answer:
511
Step-by-step explanation:
In this question numbers on either side of ':' has a relation between them which is same in each pair of numbers on either side of '::'. Choose a correct option to replace the '?'.
32 : 215 :: 62 : 1727 :: 24 : ?
32 = (3 * 2)³ - 1 = 6³ - 1 = 216 - 1 = 215
62 = (6 * 2)³ - 1 = (12)³ - 1 = 1728 - 1 = 1728
24 = (2 * 4)³ - 1 = 8³ - 1 = 512 - 1 = 511
? is replaced by 511
Logic ab : ?
? = ( a * b)³ - 1

Step-by-step explanation:
Here the explanation for the first given number lies in the structure of second number. We will find a general formula for it. Suppose the second number is cd where c is in tens place and d is in ones place. Now the relation is that (c*d)^3 - 1.
That relation when solved will be equal to the first number. Similarly if we solve that for the last question we will get.
(2*4)^3 - 1 = 511
Hence answer comes out to be 511 by using that argument equation.
