Question

Is A father is 30 years older than his son. In 12 years, the man will be three times as old as him
son. Find their present ages.​

Answer 1

Let the present age of the son be 'x' years.

Then father's age will be (x + 30) years

Given : After 12 years, the father will be three times as old as his son. Therefore, 

(x + 12)3 = x + 30 + 12

3x + 36 = x + 42

3x - x = 42 - 36

2x = 6

x = 3 

The present age of son is 3 years and the present age of the father is 3 + 30 = 33 years.

Answer.

Answer 2

Answer:

Step-by-step explanation:

Let son age be x

Father present age x+30

Acq = x+30=3(x)

X+30=3x

30=3x-x

30=2x

X=30/2x=15

Son age =15yrs

Father age=30+15

=45yrs
