Question

pooja started a business by investing rupees 200000 during the first three successive years she had an a profit 5% 8% and 12% per annum respectively if in each year the process was added on the capital at the end of the previous years calculated her total profit after 3 years

Answer 1

200000(1+5/100)
200000*21/20
2100000
=200000(1+8/100)
=200000*27/25
=8000*27
=216000
=200000(1+12/100)
=200000*28/25
=224000
=2100000+276000+224000=2600000

Answer 2

Answer: Her total profit after 3 years is 54016 rupees.

Step-by-step explanation:

Since, the principal amount, P =200000,

Annual rate,

For first year, $r_1$ = 5 %,

For second year, $r_2$ = 8 %,

For Third year, $r_3$ = 12 %,

Thus, the amount after 3 years,

$A=P(1+\frac{r_1}{100})(1+\frac{r_2}{100})(1+\frac{r_3}{100})$

$=200000(1+\frac{5}{100})(1+\frac{8}{100})(1+\frac{12}{100})$

$200000\times \frac{105}{100}\times \frac{108}{100}\times \frac{112}{100}$

$=254016$

Thus her profit after 3 years = Total amount she get after 3 years - Principal amount

= 254016 - 200000 = 54016 rupees.
