Answer 2

The loss percentage is 20%

Given : A pen is sold at Rs. 40, and there is a loss of Rs. 10

To find : The loss percentage.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the loss percentage)

First of all, we have to calculate the cost price of the pen.

As, the deal had produced a loss,

So,

Cost price = Selling price + Loss amount

By, putting the given values, we get :

Cost price = 40 + 10 = Rs. 50

Now, the loss percentage will be :

= [100 × (Loss amount / Cost price)] %

= [100 × (10/50)]%

= 20%

(This will be considered as the final result.)

Hence, the loss percentage is 20%
