Question

a General wishing to draw up his 64019 man in the form of a square found that he had 10 men extra find the number of man in the front row​

Answer 1

He is wishing to put his men in a square. So that would mean root of the total no. of men. Then he says he has 10 men extra. So that means 64019-10=64009. So men in front row=√64009=253. This is your answer.

⇒Number of men a general wishing =64019

⇒Number of extra men =10

⇒Remaining men =64019-10

⇒ 64009

⇒Number of man in front row = ✓64009

⇒Therefore , required number of men =253
