Question

army general wishes to arrange 3320 soldiers under his
command in the form of square for a parade such that number of
soldiers in a row is equal to the number of columns used in the square
formation. After arranging them he found that some of them are left out
of the formation. Find the number of soldiers that will be participating in
the parade. Also find the number of soldiers marching in each row.

Answer 1

Step-by-step explanation:

No. of soldiers =7500

Clearly it is between 85² & 90²

85²- 7225 and 90² - 8100

86 ² - 7396

87 ²- 7569

So nearest perfect square number to 7500 is 7396

So, it is 86 ²- 7396

Left out =7500−7396

=104.
