Question

The present age of a son is half the present age of his father. Ten years ago, the father was thrice as old as his son. What are their present age?​

Answer 1

Answer:

Step-by-step explanation:

Let think that present age of son is X so father will be 2X.According to the question 2X-10=(X-10)x3

2X-3X=-30+10

-X=-20

x=20

So his father is 2x20=40

Son is 20 and the father is 40 years old

Answer 2

Answer:

Let the present age of father be 'a'. So, the present age of son be 'a/2'. So, Age of son ten years ago = (a - 10)/2.
