Question

How many numbers lie between square of 12 and13

Answer 1

168 numbers will lie between square of 12 and 13

Answer 2

Hi friend!!

» Square of 12 = 144
» Square of 13 = 169

=> 13² - 12² = 169 - 144
= 25 (including 169)

But,here we need numbers which lie between them.

So,exclude 169.

Number of numbers which lie between square of 12 and 13 are 169-1 = 168

Hope it helps
