Question

Which least number must be added to 2900 to get a perfect square ?

• A. 14
• B. 12
• C. 16
• D. 18

Answer 1

The correct option is C

16

Using division method, we have

We have to add a number to 2900 such that the resultant is equal to ${54}^2$ (one more than 53).

${54}^2=2916$

So the number to be added = 2916 - 2900 = 16
