Q. Mr. Hansraj wants to find the least number of boxes to be added to get a perfect square. He already has 7924 boxes with him. How many more boxes are required?(A)819(B)412(C)419(D)176
Find Perfect Square: Determine the nearest perfect square greater than the current number of boxes.Mr. Hansraj has 7924 boxes. To find the nearest perfect square, we need to calculate the square root of 7924 and then round up to the nearest whole number.7924≈89 (since 892=7921)The next whole number is 90, and the square of 90 is 902=8100.
Calculate Difference: Calculate the difference between the nearest perfect square and the current number of boxes.To find out how many more boxes are needed, we subtract the current number of boxes from the nearest perfect square.8100−7924=176
Verify Result: Verify the result to ensure no mathematical errors were made.We found that Mr. Hansraj needs 176 more boxes to reach a perfect square of 8100. To verify, we add 176 to 7924 and check if the result is indeed a perfect square.7924+176=8100Now, we check if 8100 is a perfect square by finding its square root.8100=90Since 90 is a whole number, 8100 is a perfect square, confirming our result.
