Question

Sum of the ages of a father and his son will be 72 years after 15 years. If the age of father is
5 times than that of his son at present, find the ages of them.​

Answer 1

Answer:

Father : 35 yrs, Son : 7 yrs

Step-by-step explanation:

Let present age of father be x and that of son be y.

Given, x = 5y. --- (i)

After 15 years, Father's age = x+15 and Son's age = y+15

According to the problem,

(x+15) + (y+15) = 72

x+y=42

Putting the value of x in the above equation:

5y+y=42

6y=42

y =7 yrs

Putting the value of y in eqn i: x = 35 yrs
