Show answer & explanation
Correct answer: D
Solution: D
We need to find the approximate value of square root of 4321 using long division method or trial and error.
We find that 652 = 4225 < 4321 and 662 = 4356 > 4321
So the least number to be added = 4356 – 4321 = 35.
∴ 35 can be added to 4321 to make it a perfect square.
