Answer 1

principal invested by Pooja = 2,00,000

time = 3years

rate of profit = 5%,8% and 12% per annum.

$Amount = p(1 + \frac{r1}{100} )(1 + \frac{r2}{100} )(1 + \frac{r3}{100} ) \\ \: \: \: \: \: \: = 200000( 1 + \frac{5}{100} )(1 + \frac{8}{100} )(1 + \frac{12}{100} ) \\ \: \: \: \: \: \: = 200000 \times \frac{105}{100} \times \frac{108}{100} \times \frac{112}{100} \\ \: \: \: \: \: \: = \frac{2 \times 105 \times 108 \times 112}{10} \\ \: \: \: \: \: \: = 254016$

Amount = 254016

Profit = 254016-200000 = 54016
