Question

By selling a watch in Rs 150 and Rs 200 loss and profit are happened

respectively. If the loss and the profit are equal, find its cost price.​

Answer 1

Rs 175

Explanation:

Suppose the cost is x and at Rs150 the loss is 150-x (this should be a negative number).

At Rs200, the profit is 200-x.

So we have an equation: minus 150 minus x is equal to 200 minus x.

To solve the equation, the cost price X is Rs175.
