The age of father is three times of his son. Six years ago the age of son was 1/6 times of his father. At the time of marriage his mother was 5 years younger to his father. Find the present age of mother.
Answer & explanation
Correct answer: option 3
Let present age of son = x
Then according to question age of father is 3 times of age of son at present .
i.e. age of father = 3x
6 years ago, the age of son is \(\frac{1}{6}\) of age of father .
(3x - 6 )= 6 ( x - 6 )
3x - 6 = 6x - 36
3x = 30
x= 10
Age of father = 3x = 30 years
As it is mentioned in question that his mother is 5 years younger to his father . At present she is also 5 years younger to his father .
So, age of mother = 30 - 5 = 25 years
