Question

What sum of money will amount to 1748 in 5/2 years at the rate of 15/2 %per annum simple interest

Answer 1

♥ GIVEN ♥

$amount = 1748 \\ time = \frac{5}{2} years = 2.5years \\ \\ rate \: of \: interest = \frac{15}{2} \% \: p.a \:$

♥ FORMULA USED ♥

$s.i = \frac{p \times r \times \: t }{100}$

♥ SOLUTION ♥

$let \: the \: sum \: be \: x \\ \\ s.i = \frac{p \times r \times t}{100} \\ \\ \: \: \: \: \: \: = \frac{x \times 7.5 \times 2.5}{100 } \\ \\ \: \: \: \: \: \: = \frac{18.75x}{100} \\ \\ s.i = 0.1875x$

$amount = p +s .i \\ \\ = > 1748 = x + 0.1875x \\ \\ = > 1748 = 1.1875x \\ \\ = > 1.1875x = 1748 \\ \\ = > x = \frac{1748}{1.1875} \\ \\ = > x = 1472$

♥ So,sum of money (p) is RS.1472 ♥
