Question

A grocer has a sale of $Rs.6435,Rs.6927,Rs.6855,Rs.7230$ and $Rs.6562$ for $5$ consecutive months. How much sale must he have in the sixth month so that he gets an average sale of $Rs.6500$?

• A. $Rs.4991$
• B. $Rs.5991$
• C. $Rs.6001$
• D. $Rs.6991$

Answer 1

The correct option is A $Rs.4991$

Total sale of $5months=Rs.(6435+6927+7230+6562)=Rs.34009$.
$\therefore$ Required sale $=Rs.\left[\right(6500\times 6)-34009]$
$=Rs.(39000-34009)$
$=Rs.4991$.
