Answer: Pooja's age = 8 yrs
Father's age = 32 yrs
Step-by-step explanation:
Let Pooja's age be x
Let father's age be y
According to the question,
y = 4x -------- (1) { Current }
(y-5) = 9 (x-5) -------- (2) { 5 years ago }
y - 5 = 9x - 45
9x - y = 40 -------- (3)
Substituting equation (1) : y = 4x,
9x - 4x = 40
5x = 40
x = 40/5
∴ x = 8
From equation, y = 4x
∴ y = 32
Thus Pooja's age is 8 years and her father's age is 32 years.
Hope this helps.
