Question

13. A father is 20 years older than his son. After 5 years the age of father will be twice of his son. Find the present age of Father and son? a)25, 10 d)35, 15 b)40, 15 c)35, 17 ​

Answer 1

Answer:

35,15

Step-by-step explanation:

Let the present age of son = x years

So, present age of the father = x + 20 years

After 5 years, the age of son = (x + 5) years

After 5 years, the age of father = (x+20+5) years = (x+25) years

Now, according to the question, After 5 years the age of father will be twice of his son.

Therefore, (x+25) = 2(x+5)

  => x + 25 = 2x + 10

=> 2x - x = 25 - 10

=> x = 15

Therefore, present age of son = 15 years

And present age of the father = 15+20 = 35 years.
