Q. Mr. Hansraj wants to find the least number of boxes to be added to get a perfect square. He already has 79247924 boxes with him. How many more boxes are required?\newline(A)819(A)819\newline(B)412(B)412\newline(C)419(C)419\newline(D)176(D)176
  1. Find Perfect Square: Determine the nearest perfect square greater than the current number of boxes.\newlineMr. Hansraj has 79247924 boxes. To find the nearest perfect square, we need to calculate the square root of 79247924 and then round up to the nearest whole number.\newline792489\sqrt{7924} \approx 89 (since 892=792189^2 = 7921)\newlineThe next whole number is 9090, and the square of 9090 is 902=810090^2 = 8100.
  2. Calculate Difference: Calculate the difference between the nearest perfect square and the current number of boxes.\newlineTo find out how many more boxes are needed, we subtract the current number of boxes from the nearest perfect square.\newline81007924=1768100 - 7924 = 176
  3. Verify Result: Verify the result to ensure no mathematical errors were made.\newlineWe found that Mr. Hansraj needs 176176 more boxes to reach a perfect square of 81008100. To verify, we add 176176 to 79247924 and check if the result is indeed a perfect square.\newline7924+176=81007924 + 176 = 8100\newlineNow, we check if 81008100 is a perfect square by finding its square root.\newline8100=90\sqrt{8100} = 90\newlineSince 9090 is a whole number, 81008100 is a perfect square, confirming our result.
