Question

the sum of the digit of two digit number is 15. if the number formed by reversing the digit is less the original number by 27, find the original number.​

Answer 1

Let unit digit be 'x'

Ten's digit be 'y'

Original number = 10*y+x

Reversed number =10*x +y

A/Q x+y=15

10y+x-10x-y=27

Or y-x=3

Hence, y=9

x=6

Original number =96
