Question

A fruit vendor goes to a wholesale market and picks up $2$ dozen apples for $Rs.600$ from one shop, $1\frac{1}{2}$ dozen apples at $Rs.26$ each from another shop, and 18 apples for $Rs.432$ from yet another shop. How much did he pay for each apple on average.

Answer 1

$1$ dozen $=12$ apples

$\Rightarrow 2\left(12\right)$ apples $\Rightarrow Rs600---\left(1\right)$

and $1.5\left(12\right)$ apples $\Rightarrow Rs26each----\left(2\right)$

and $18$ apples $\Rightarrow Rs432----\left(3\right)$

from $\left(1\right),1$, apple $=A_1=\frac{600}{24}=25$

$\left(2\right),1$, apple $=A_2=Rs26$

$\left(3\right),1$, apple $=A_3=\frac{432}{18}=24$

$\therefore$ Average $\Rightarrow \frac{A_1+A_2+A_3}{3}=\frac{25+26+24}{3}$

$=25$
