Question

5. Ruchi borrowed * 18,000 from her friend at the rate of 12% per annum at simple interest. She lent it
further to another friend Aarti at the same rate but compounded annually. Find the profit that Ruchi
earns after 2 years.​

Answer 1

Step-by-step explanation:

$simple \: interest \: for \: ruchi = \frac{18000 \times 12 \times 2}{100} = 4320$

$amount \: for \: aarti = 18000{( \frac{12}{100} + 1)}^{2} = 18000 \times \frac{112}{100} \times \frac{112}{100} = 22,579.2$

$c.i \: for \: aarti =22579.2 - 18000 = 4579.2$

$profit \: that \: ruchi \: earn = 4579.2 - 4320 = 259.2$
