Answer 2

Given:

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%.

To Find :

After two years they  exchanged their belongings and one paid the other the  difference. Then

Solution:

Ram purchased a flat at Rs. 1 lakh

The respective annual  rates at which the prices of the flat and the plot  increased were 10% and 5%.

So, Cost of flat after 2 years = 100000(1+0.1)^2=121000

Prem purchased a  plot of land worth Rs. 1.1 lakh.

So, cost of plot after 2 years = 110000(1+0.05)^2=121275

Difference between prices = 121275-121000=275

Hence Ram paid Rs. 275 to Prem
