Question

Find the SI P = 4500,R =
$\frac{15}{4}$
T =3 year 4months​

Answer 1

Given;

• P = 4500 Rs.
• R = 15/4
• T = 3yrs 4 months

4 months = 4/12 year => 1/3 year.

Thus total time T ;

$3 + \frac{1}{3} \\ \frac{9 + 1}{3} \\ \frac{10}{3} years$

T = 10/3 years

Thus for SI ;

$SI \: = \frac{PRT}{100} \\ = \frac{4500 \times \frac{15}{4} \times \frac{10}{3} }{100} \\ = \frac{4500 \times 15 \times 10}{100 \times 12} \\ \\ = \frac{45 \times 15 \times 10}{12} \\ = \frac{45 \times 5 \times 10}{4} \\ = \frac{225 \times 10}{4} \\ = \frac{2250}{4} \\ = 562.5 \: Rs.$
