Question

The age og Ramesh,Suresh and Kalpesh are 16 years 7 months, 13 years 3 months and 15 years 2 months respectively. What is average og their age.

Answer 1

Age of Ramesh = 16 years 7 months = $16\frac{7}{12}=\frac{199}{12}\mathrm{years}$
Age of Suresh = 13 years 3 months = $13\frac{3}{12}=\frac{159}{12}\mathrm{years}$
Age of Kalpesh = 15 years 2 months = $15\frac{2}{12}=\frac{182}{12}$ years
So, average of their age = $\frac{{\displaystyle \frac{199}{12}}+{\displaystyle \frac{159}{12}}+{\displaystyle \frac{182}{12}}}{3}=\frac{199+159+182}{36}=\frac{540}{36}=15$
Therefore the average of their age is 15 years.
