A father is five times as old as his son, but after 15 years, he will remain only twice as old as his son. What is the age of the father?

Explanation

Join@Apnapdfs (447) ## Page 46 Let the age of son = x then, the age of father = 5x According to the question after 15 year- $$(5x + 15) = 2 \times (x + 15)$$ $$5x + 15 = 2x + 30$$ $$3x = 30 - 15$$ $$3x = 15$$ $$x = 5$$ Now the age of Father = $5 \times 5 = 25$ years
