Best answer

**After 2 years the price of the flat will be**

1,00,000 * (1 + 10/100)^{2 }= 1,00,000 * (11/10)^{2 }= 1,21,000 [Calculated in compound interest]

**After 2 years the price of the plot of land will be**

1,10,000 * (1 + 5/100)^{2} = 1,10,000 * (105/100)^{2} = 121275 [Calculated in compound interest]

So, the plot has higher price than the flat.

Therefore, **Ram will pay** (121275 - 121000) = **275 rs. to Prem**
