after 4 years the age of father is twice as well as his son five years before the father age was one year more than triple age of

1 thought on “after 4 years the age of father is twice as well as his son five years before the father age was one year more than triple age of”

1. Let the age of son be x.

   Thus, age of father is 4x.

   After 5 years, their ages will be x+5 and 4x+5 years respectively.

   As per the question, we have

   4x+5=3(x+5)

   ⇒4x+5=3x+15

   ⇒x=10

   Age of father will be 4x=4×10=40 years.

   Thus when son is 10 years old, father is 40 years.

   Hope this will help you
