Ram purchased a flat at Rs. 1 lakh and Prem purchased a plot of land worth Rs. 1.1 lakh. The respective annual rates at which the prices of the flat and the plot increased were 10% and 5%. After two years they exchanged their belongings and one paid the other the difference. Then  Choose the correct option
A) Ram paid Rs. 275 to Prem  B) Ram paid Rs. 475 to Prem  C) Ram paid Rs. 375 to Prem  D) Prem paid Rs. 475 to Ram  E) None of these
Explanation :   After 2 years the price of the flat will be (1)(1.10)2 = Rs. 1.21 lakh.   Correspondingly the price of the land will be (1.1)(1.05)2 = Rs. 1.21275 lakh.   Hence, the price of the plot is Rs. (1.21275 – 1.21) lakh = Rs. 275 more than that of the flat. Hence, if they exchange, Ram will have to pay Prem this amount.   Ram paid Rs. 275 to Premnswer : Ram paid Rs. 275 to Prem
