Question

If the present age of father is $52$ years and that of his son is $18$ years, then

(Age of father after $10$ years) : ( Age of son after $13$ years)$=$________

Answer 1

Given that,

Present age of father $=52years$

Present age of son $=18years$

Age of father after $10$ years$=52+10=62years$

Age of son after $13$ years $=18+13=31years$

Now, Ratio of age of father after $10$ years to Age of son after $13$ years $=62:31$

Lowest form of $62:31=\frac{62}{31}=\frac{2}{1}=2:1$ ( Divide both $62$ and $31$ by their HCF $31$)

Hence, (Age of father after $10$ years) : ( Age of son after $13$ years)$=$$2:1$
