Step-by-step explanation:
Ratio of present ages of mother and daughter = 5 : 1
Ratio of ages of mother and daughter after 6 years = 3 : 1
Concept Used:
The difference between ages of two persons at any time is constant.
Calculation:
Let the present ages of Mother and Daughter be 5x and x
After 6 years their ages will be 5x + 6 and x + 6
According to the question-
(5x + 6)/(x + 6) = 3/1
⇒ 5x + 6 = 3x + 18
⇒ x = 6
∴ The present age of daughter is 6 years.
