Question

find the cost price, when selling price =690 , profit =15%​

Answer 1

Given :

Selling Price (SP) = 690

Profit = 15%

To Find :

The Cost Price (CP)

Solution :

Cost Price (CP) = $\frac{SP X 100 }{100 + Profit}$

                         = $\frac{690 X 100}{100 + 15}$

                         = $\frac{69000}{115}$

                         = Rs 600

The Cost Price (CP) is Rs 600.

Answer 2

Given

The selling price or sp =690

The profit percentage is given as 15%

To find

The cost price of the object

Solution

The solution to the above problem can be easily found by using the basic mathematical equation to find the selling price

The solution to the above problem is as follows

So the equation for cost price is   $\frac{sell.price*100}{Profit+100}$

Which we get it as    $\frac{690* 100}{15+100}$  = 600rs

So the final cost price of the object = 600rs
