The age of a father 5 years ago was 7 times the age of his son. At present, the age of the father is 5 times the age of his son. Find the age of son .
Answer & explanation
Correct answer: option 2
Let the present age of son be x
Present age of father will be 5x
According to question,
\(\frac{x - 5}{5x-5}\) = \(\frac{1}{7}\)
7x - 35 = 5x - 5
2x = 30
x= 15 years
So, age of son is 15 years.
