Question

Solve (with steps)-
The age of my father is the same as my mother with the digits reversed. The sum of their ages is 99, and the father is 9 years older than my mother. How old is my father.

Answer 1

Hello friend,
Let father's age be xy or (10x+y)
10x+y-(10y+x)=9
9x-9y=9
x-y=1
xy+yx=99
So by trial method,
we get value as 54 and 45.
hope it helps.
