A mother is 5 times as old as her daughter. After 5 years her age will be 3 times that of her daughter. What is the mother's present age?
Answer & explanation
Correct answer: option 3
Let the age of daughter = x
Age of mother = 5x
after 5 years ,
according to question
3 ( x + 5 ) = 5x + 5
3x + 15 = 5x + 5
2x = 10
x = 5 years
therefore age of mother = 5 × 5 = 25 years
