Question

Age of John's father is three times the age of John.Five years ago, age of father was four times John's age at that time. Find their present ages.​

Answer 1

Step-by-step explanation:

Suppose,

The age of John's father is F.

The age of John is S

F=3S

Five Years Ago,

F-5=4(S-5)

Now, we will put the value of Father in the second equation.

3S-5=4S-20

S=15 years

Age of John = 15 Years

Age of Johns Father = 3S = 45 years
