A man bought 25 crates of oranges for 10000. He lost 5 crates. In order to earn a total profit of 25% of the total cost, he would have to sell each of the remaining crates at = ?

Solution (By Examveda Team)

Remaining creates = 25 - 5 = 20
So,
$$\eqalign{ & {\text{Cost Price}} \cr & = \frac{{10000}}{{20}} = 500/{\text{crates}} \cr & {\text{25}}\% = \frac{{1 \leftarrow {\text{Profit}}}}{{4 \leftarrow {\text{Cost price}}}} \cr & \,\,\,\,\,\,{\text{CP}}\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{\text{SP}} \cr & \mathop { \downarrow \times 125}\limits_{500\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,}^{4\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \mathop {\,\,\,\,\, \downarrow \times 125}\limits_{625\,\,\,\,\,\,\,\,\,\,\,}^{5\,\,\,\,\,\,\,\,\,\,\,} \cr} $$
Sell each of the remaining crates = Rs. 625
