Question

A two digit number is 36 more than the number obtained by reversing the digits. If difference between tens digit and unit digit is 4. Find the number

Answer 1

Let the unit digit be x
and tens digit be y
so the number is 10y+x
reversing digits the number becomes 10x+y

10y+x= 36+ (10x+y)

also y-x=4o

solving this both equation to get the answer
Hope this helps
