Question

Jacks's age is 3 times the age of his daughter. 10 years ago, Jack was 5 times the age of his daughter. Find their present ages

Answer 1

Answer:

Jack's daughter's present age is 20 years and Jack's present age is 60 years.

Step-by-step explanation:

Let the daughter's age be 'x'

Then, Jack's age=3x

A/Q,

3x-10=5(x-10)

=>3x-10=5x-50

=>5x-3x=50-10

=>2x=40

∴ x = 20

Therefore, Jack's daughter's present age is 20 years and Jack's age is 3x=3*20=60 years.

Hope it helps!
