The simple interest on a certain sum of money for 2(1/2) years at 12% per annum is Rs.40

shepuryov [24]

Step-by-step explanation:

$si = p \times \frac{r}{100} \times t$

$si = 40 \times \frac{12}{100} \times \frac{5}{2}$

$si = \frac{40 \times 12 \times 5}{100 \times 2}$

$si = \frac{4 \times 12 \times 5}{10 \times 2}$

$si = \frac{4 \times 12 }{5\times 2}$

$si = \frac{2 \times 12}{5}$

$si = \frac{24}{5}$

$si = 4.8$
