Rita buys 5 sarees at an average cost of Rs. 2250. If she buys three more at an average cost of Rs. 2750, what will be the average (in Rs.) of all the sarees she buys?

Solution (By Examveda Team)

$$\eqalign{ & {\text{Average of all the sarees}} \cr & = \frac{{2250 \times 5 + 2750 \times 3}}{8} \cr & = \frac{{11250 + 8250}}{8} \cr & = \frac{{19500}}{8} \cr & {\text{Average of all the sarees}} = 2437.5 \cr} $$
