A mother is 4 times as old as her daughter. After 4 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 = 4x
after 4 years ,
according to question
3 ( x + 4 ) = 4x + 4
3x + 12 = 4x + 4
x = 8 years
therefore age of mother = 8 × 4 = 32 years
