Solution
Profit at the end of the first year = P \[\left( 1 + \frac{R}{100} \right)\]
\[ = 2, 500, 000\left( 1 + \frac{5}{100} \right)\]
\[ = 2, 500, 000\left( 1 . 05 \right)\]
\[ = 2, 625, 000\]
Profit at the end of the second year = P \[\left( 1 + \frac{R}{100} \right)\]
\[ = 2, 625, 000\left( 1 + \frac{10}{100} \right)\]
\[ = 2, 625, 000\left( 1 . 10 \right)\]
\[ = 2, 887, 500\]
Total profit = Rs 2, 887, 500 - Rs 2, 500, 000
= Rs 387, 500
