Question

What is aman's present age, if after 20 years his age will be 10 times his age 10 years back?

Answer 1

Answer,

Let Aman's present age be x

Aman's age before 10 years = (x - 10)

Aman's age after 20 years = (x + 20)

According to question,

Aman's age after 20 years (x + 20) is 10 times his age 10 years back (x – 10)

Therefore, (x + 20) = 10 (x – 10)

Solving the equation,

we get x + 20 = 10x – 100

9x = 120,

x = 13.3 years
