Question

a two digit number is 36 more than the number obtained by reversing the digits if diffrence between ten's digit and unit's digit is 4 find the number

Answer 1

let the given no is 10y+x

the number obtained by reversing the digit

=10x+y

So

10y+x-10x-y=36

9y-9x=36

y-x=4

so y= 4+x

10y+x=40+11x
