Question

the sum of ages of a son and father is 72 years. after 12 years the age of father will be 3 times of the son. what is the age of son now? ​

Answer 1

Answer:

12 years

Step-by-step explanation:

Let the current ages of father and son be x and y respectively.

Then x+y=72

After 12 years, x+12=3(y+12)

Take x=3y+36-12 == x=3y+24 and substitute in x+y=72.

We get 4y=48 so y=12.

The age of son now is 12 years.
