A machine is bought for ₹3800 and ₹700 is paid for loading and it is sold for ₹3800. Find the percentage of gain or loss. 

Given :

The cost price of a machine $= 3800$.

Transportation charges $= 700$.

The selling price of a machine $= 3800$.

To do :

We have to find the gain or loss percentage.

Solution :
 

Cost price $+$ Transportation charges $= 3800 + 700 = 4500$.

Seling price $=3800$.

So, there occurred a loss.

Loss % $= \frac{700}{4500} \times 100$

          $=\frac{700}{45}=15.55$

Therefore, the percentage of loss is 15.55%
