At present Meena is eight times her daughter's age. 8 yr from now, the ratio of the ages of Meena and her daughter will be 10 : 3, respectively. What is Meena's present age?
Correct Answer: 32 yr
Explanation:
Let age of daughter = N yr
∴ Age of Meena = 8N yr
Accounting to the question, (8N + 8)/(N + 8) = 10/3
⇒ 24N + 24 = 10N + 80
⇒ 14N = 56
∴ N = 4
Hence, Meena's present age = 4 x 8 = 32 yr
