Question

The marked price of a watch is Rs. 1600. If it is sold at a discount of 10%, the profit is Rs. 80, what is the cost price of the watch? ​

Answer 1

In context to questions asked

We have to determine the value of cost price of the watch

As per questions

MRP = Rs 1600

Discount = 10%

As we have the formula for calculating SP

$sp = \frac{100 - d}{100} \times mrp$

So putting the value in above equation

We will get,

$sp = \frac{100 - 10}{100} \times 1600 \\ = > sp = \frac{90}{100} \times 1600 \\ = > sp = 1440 \: rs$

As there is profit of Rs 80

So for calculating the value of CP we will subtract profit from SP

thus we will get

$cp = 1440 - 80 = 1360 \: rs$
