Q. A person sold two cows each for Rs. 9900. If he gained 10% on one and lost 20% on the other, then which of the following is true ?
The cost price ( CP ) of profitable cow = 9900 / 1.1 = 9000 and profit = Rs. 900 The CP of loss yielding cow = 9900 / 0.8 =12375 and loss = Rs. 2475 So the net loss = 2475 - 900 = 1575
