Answer 1

Answer:

90,30

Step-by-step explanation:

Now: Son age is x. Father’s age is 4x.

In 10 years Father will be 4x+10, son x+10.

Father will be 3 times of son’s age or

4x+10=3(x+10).

Solving this x=20.

Therefore father’s age now is 4x20=80.

in 10 years: Father will be 90 and son will be 30
