Question

• A. $101$
• B. $34$
• C. $238$
• D. $121$
• E. None of these

Answer 1

The correct option is A $101$

Given number is $4523$.

We know that, $(67{)}^2=4489$ and $(68{)}^2=4624$

Hence, for making $4523$ a perfect square, it has to become $4624$.

Also, $4624-4523=101$

Hence, $101$ must be added to $4523$ to make it a perfect square.
