Answer 1

Correct Answer - Option 2 : 12

Given:

We have to find the smallest number that should be subtracted from 2209 to get a perfect cube number

Calculation:

The nearest perfect cube number from 2209 is 2197 (the cube of 13)

So the least number which must be subtracted from 2209 to make a perfect cube is:

⇒  (2209 ─ 2197) = 12

∴ The number is 12.
