When u reverse the digits of age of father u will get the age of son.
10x + y = father's age
10y + x = son's age
:
one year ago the age of father was twice that of son's age.
10x + y - 1 = 2(10y + x - 1)
10x + y - 1 = 20y + 2x - 2
10x - 2x = 20y - y - 2 + 1
8x = 19y - 1
x = y -
Only one set of single digit integers will satisfy this equation
y = 3; x = 7
