Answer 2

Answer:

Current age of Monica=6 years

and current age of William=18 years

Step-by-step explanation:

Let Monica's current age be x years and William's current age be y years.

William is 3 times elder than Monica.

⇒  y=3x

In 6 years William will be twice as old as Monica.

⇒ y+6=2(x+6)

⇒ y+6=2x+12

⇒3x+6=2x+12

⇒ x=6

Hence, y=3×6=18

That means, current age of Monica=6 years

and current age of William=18 years
