Question

What's the answer of this question ?

Answer 1

Answer:

Son = 10 years old, father = 50 years old

Step-by-step explanation:

Let present age of son be x

∴ present age of father = 5x [5 times of x]

After 10 years Son's age = x + 10

After 10 years father's age = 5x + 10

According to question

Father's age after ten years = 3 times ( son's age after 10 years)

5x + 10 = 3 ( x + 10)

5x + 10 = 3x + 30

2x = 20

x = 10

∴ Present age of Son = 10 years

and father's present age is (5x) = 50 years
