Question

2) Ram invested a certain amount of money for 3 years at 8% per annum. The simple
interest earned by him is half the compound interest on 34,000 for 2 years at 10% per
annum. Find the simple interest earned by Ram.
be offers 30%​

Answer 1

Step-by-step explanation:

$amount = principle \times ({1 + \frac{r}{100} )}^{time}$

$= 34000 \times {(1 + \frac{10}{100} })^{2} = 34000 \times \frac{121}{100}$

$= 340 \times 121 = 41140$

$compound \: interest = 41140 - 34000 = 7140$

Interest Ram get=7140/2=3570

$principle \: = \frac{simple \: interest \times 100}{time \: \times rate}$

$principle = \frac{3750 \times 100}{8 \times 3} = 15625$

If the rate become 30% interest will be

$= \frac{p \times r \times t}{100} = \frac{15625 \times 30 \times 3}{100} = 14062.5$
