Question

Find the time when:
Principal = Rs. 3560, Amount = Rs. 4521.20 and time = 3 years.

✓

Answer

Principal (P) = Rs. 3560
Amount (A) = Rs. 4521.20
S.I. = A - P
= Rs. 4521.20 - 3560
= Rs. 961.20
Time (t) = 3 years.
$\therefore\text{Rate}=\frac{\text{S.I.}\times100}{\text{P}\times\text{r}}$
$=\frac{961.20\times100}{3560\times3}$
$=9\%\text{ p.a.}$
