Question

The ratio of a father’s age to his son’s age is 4 :1 .The product of their ages is 196 .What is the

ratio of their ages after 5 years​

Answer 1

Answer:

Let the age of son be x

let the age of father be 4x

at present,

4x * x = 196

x^2 = 49

x = 7

son = 7 years

father = 28 years

after 5 years,

son = x + 5 = 12

father = 4x + 5 = 33
