Answer 1

Answer:

17520

Step-by-step explanation:

solution ------>

Given :-

• Principle = 8000
• year 2 = n
• R % =9% for 1st year
• R = 10% for 2nd year

now as we all know

formula of amount

$a \: = p \times {(1 + \frac{r}{100})}^{n} \\ \\ put \: all \: the \: value \: as \: per \: 1st \: condition \\ \\ a = 8000 \times {(1 + \frac{9}{100})}^{1} \\ \\ a = 8000 \times \frac{109}{100} \\ \\ a = 80 \times 109 \\ \\ a = 8720 \\ \\ now \: as \: per \: 2nd \: condition \\ \\ a \: = p \: \times {(1 + \frac{r}{100})}^{n} \\ \\ a = 8000 \times {(1 + \frac{10}{100})}^{1} \\ \\ a = 8000 \times \frac{110}{100} \\ \\ a = 80 \times 110 \\ \\ a = 8800$

if we total the both

17520
