SOLUTION:-

Given:

•A vendor bought 6 oranges for Rs.10 &

•Sold them at 4 oranges for Rs.6.

To find:

The loss or gain percent.

Explanation:

We have,

Cost price of 6 oranges= Rs.10.

Cost price of 1 oranges= Rs.10/6

Cost price of 1 oranges= Rs.5/3

&

Selling price of 4 oranges= Rs.6

Selling price of 1 oranges= Rs.6/4

Selling price of 1 orange= Rs. 3/2

Using the formula of the loss:

Loss= Cost price - selling price
