Answer by ashishtayal(3)   (Show Source):
You can put this solution on YOUR website! Let father age = x years
thus, boy age = x/4 years
x + x/4 < 80
5x/4 < 80
5x < 320
x<64
So, possible solutions are
Father's age = 60 years, Boy's age = 15 years
Father's age = 56 years, Boy's age = 14 years
Father's age = 52 years, Boy's age = 13 years
Father's age = 48 years, Boy's age = 12 years
Father's age = 44 years, Boy's age = 11 years
Father's age = 40 years, Boy's age = 10 years
Father's age = 36 years, Boy's age = 9 years
Father's age = 32 years, Boy's age = 8 years
Father's age = 28 years, Boy's age = 7 years
Father's age = 24 years, Boy's age = 6 years
Father's age = 20 years, Boy's age = 5 years
