Radha got married six years ago. Her present age is $\frac{5}{4}$ times of her age at the time of marriage. Her daughter's age is $\frac{1}{10}$ of her age. What is the present age of her daughter?
Answer & explanation
Correct answer: option 3
Let's assume present age of Radha = X yrs.
so, the age of Radha at the time of marriage = (X - 6)yrs.
=> X = 5/4 (X - 6)
=> X/4 = 15/2
=> X = 30
therefore, the present age of Radha is 30yrs
and, the present age of Radha's daughter is 30/10 = 3yrs.
