(a) Let the purchased amount be 1100 kg and the cost price of 1100 kg be Rs. x.
Therefore, he pays for 1000 kg and buys 1100 kg.
Cost price of 1000 kg =Rs.(10/11) x
Therefore, net profit = Rs. x/11
Similarly while selling, if he sells 1000 kg. He would actually be selling 900 kg at the price of 1000 kg.
Similarly, once again the profit would be Rs.x/11
Therefore, total profit = Rs. 2x /11
In terms of percentage, this would be 200/100%
