Answer : 4% Loss

_______________________

Solution :

There are two ways to solve this question :

(1) First method :

The cost price of the house which is sold on the 20% gain = 9600 × 100/(100+20) = Rs. 8000

The cost price of the house which is sold as 20% loss = 9600 × 100/(100-20) = Rs. 12000

Then, Total cost price = 8000 + 12000 = Rs. 20,000

Total Selling Price = 9600 + 9600 = Rs. 19200

Loss = 20000 - 19200 = Rs. 800

Loss% = 800/20000 × 100 = 4%

(2) Second Method :

Gain% - Loss% - (Gain%×Loss%)/100

=> 20 - 20 - (20×20)/100 = -4 = 4% Loss
