Answer 2

Answer:

The present age of father is 80 years and the present age of son is 20 years.

Step-by-step explanation:

Let the present age of father be X and of son be Y.

According to given condition

X = 4Y

According to the second condition

X + 10 = 3 ( Y + 10 )

Therefore

X + 10 = 3Y + 30

Substitute X = 4Y in the above equation

4Y - 3Y = 30 - 10

Y = 20 years.

Therefore X = 4Y

                    = 4 x 20

                    = 80 years

The present age of father is 80 years and the present age of son is 20 years.
