A general wishing to draw up his 16160 soldiers in the form as a solid square, found that he had 31 soldiers left over. Find the number of soldiers in the front.?
Correct Answer: 127
Explanation:
Let the total number of soliders in front be x. Then, total number of soliders in form of solid square = x2
According to the question, x2 + 31 = 16160
⇒ x2 = 16129 ⇒ x = √16129
∴ x = 127
