Question

give me answers and solutions

Answer 1

simple interest
$\frac{60000 \times 9 \times 3}{100} = 16200 \\ 60000 - 16200 = 43800$
60000 - 43800
16200
compound interest
$60000(1 + \frac{9}{100} ) {}^{3} \\ 60000( \frac{109}{100}) {}^{3} \\ 60000 \times \frac{109}{100} \times \frac{109}{100} \times \frac{109}{100} \\ 6 \times 109 \times 109 \times \frac{109}{100 } \\ a = 77701.74$
interest =77701.74 - 60000
= 17701.74
difference =17701.74 - 16200
1501.74
so the difference between compound and simple interest is 1501.74
