Answer:
Let Jack = x
Let Jill = y
According to the question
x = 3y ---- (i)
In 3 yrs time
Jack = x+3
Jill = 2(y+3)
⇒Jill = 2y + 6
Acc. to the question
x + 3 = 2y + 6
⇒ x - 2y = 3 ----- (ii)
Substituting the value of equation (i) in (ii)
⇒ 3y - 2y = 3
⇒ y = 3
Putting value in equation (i)
x = 3 * 3
⇒ x = 9
∴ Jack(x) = 9 and Jill(y) = 3
