Question : 44 of 200

Marks: +1, -0

Adam who is 20 years old is 4 times as old as Mary. What will be Mary’s age when Adam is twice as old as her ?

Solution:

Adam's age = 20 years
⇒ Mary's age =

20/4=5

years
Since, difference between their ages =

20-5=15

years
∴ Mary's age will be years when Adam is twice as old as her. (i.e. after 10 years)
