Solution

Investment in the beginning
Profit during the first 2 years $= 5 %$ and $10 %$ respectively.
$∴$ Investment after 2 years will be
$= R s . 2500000 (1 + \frac{5}{100}) (1 + \frac{10}{100})$
$= R s . 2500000 \times \frac{21}{20} \times \frac{11}{10}$
$= R s . 2887500$
$∴$ Amount of profit
= Rs. 2887500 - Rs. 2500000
= Rs. 387500
