Question

Answer 1

Answer:

it's 15

Explanation:

a simple trick in maths..

if any two digit number ends with 5 suppose take 25 ,last number would be 25(5 square) and first digit(s) would be the product of number at tens place and it's succeeding number..since in example it's 25,so 2x3=6...so the number is 25²=625..

similarly 35²=1225

45²=2025

55²=3025

65²=4225

75²=5625..

by this... 15²=225

hope it helps you..

have a nice day
