A horse and cow were sold for Rs.12000 each. The horse was sold at a loss of 20% and the cow at a gain of 20%. The entire transaction resulted in : Options:
A) No loss or gain  B) Loss of Rs.1000  C) Gain of Rs.1000  D) Gain of Rs.2000  E) None of these
Explanation:   In the special case of profit and loss percentages are equal and Selling price is same, then the transaction always results in Loss. This loss percentage is given by a simple formula −(x/10)2   So in this case, Profit% = Loss% = 20. So x = 20   Loss percentage = −(20/10)2=−4   Total S.P = Rs.24000   Cost price = 24000×100/96 = 25000   Loss = Rs.1000   Correct Option : Loss of Rs.1000
