Question

If 10 years , Anup will be twice as old as Bunny was 10 years ago. If Anup is now 9 years older than Bunny . the present age of Bunny is

Answer 1

the age of bunny is 19

Answer 2

Define current age:

Let Bunny be x years old

Anup is (x + 9) years old

Express their age in 10 years time:

Bunny = x + 10

Anup = x + 9 + 10 = x + 19

Solve x:

Anup will be twice as old as Bunny was 10 years ago

⇒ x + 19 = 2(x + 10 - 10)

Solve x:

x + 19 = 2(x + 10 - 10)

x + 19 = 2(x)

x + 19 = 2x

x = 19

Answer: Bunny is 19 years old now.
