Let father's age be 4T and son's age T years.
∵ 4T x T = 196
Let father's age be 4T and son's age T years.
∵ 4T x T = 196
⇒ T^{2} = 49
∴ T = 7
Father's age after 5 years = (4T + 5) = 33 years
Son's age after 5 years = (T + 5) = 12 years
∴ Ratio of their ages after 5 years = 33 : 12 = 11 : 4

∵ 3x + 5x = 80
⇒ x = 10
Ratio of their ages after 10 years = (3x + 10) : (5x + 10)
∵ 3x + 5x = 80
⇒ x = 10
Ratio of their ages after 10 years = (3x + 10) : (5x + 10) = 40 : 60 = 2 : 3
