Q. Neela is now 3 times as old as her daughter Leela. Ten years back, Neela was 5 times as old as Leela. The age of Leela is
✅ Correct Answer: (D)
20
Explanation: Suppose the present age of Leela is P years.
Therefore, the present age of Neela = 3P years
10 years ago ,5 × ( the present age of Leela - 10 years ) = ( the present age of Neela - 10 years )
5 (P – 10) = (3P – 10)
⇒ 5P – 50 = 3P – 10
⇒ 5P – 3P = 50 – 10
⇒ 2P = 40
P = 20

Suppose the present age of Leela is P years.
Therefore, the present age of Neela = 3P years
10 years ago ,5 × ( the present age of Leela - 10 years ) = ( the present age of Neela - 10 years )
5 (P – 10) = (3P – 10)
⇒ 5P – 50 = 3P – 10
⇒ 5P – 3P = 50 – 10
⇒ 2P = 40
P = 20
Therefore, the present age of Neela = 3P years
10 years ago ,5 × ( the present age of Leela - 10 years ) = ( the present age of Neela - 10 years )
5 (P – 10) = (3P – 10)
⇒ 5P – 50 = 3P – 10
⇒ 5P – 3P = 50 – 10
⇒ 2P = 40
P = 20
