Question

Four sets are given out of which three are alike in some manner while one is different. Choose the one which is different from the rest three.

• A. $64,8,27$
• B. $349,625,524$
• C. $512,1000,216$
• D. $125,216,729$

Answer 1

The correct option is B $349,625,524$

Each group of numbers except B, contains the numbers which are perfect cube of some natural number.

Example, $64=4^3$, $8=2^3$, $27=3^3$.

But in B, none of the numbers are perfect cube of natural numbers.
Hence, option (B) is the correct answer.
