Question
Find the time when:
Principal = Rs. 8250, S.I. = Rs. 1100 and time = 2 years.
✓

Answer

Principal (P) = Rs. 8250
S.I. = Rs. 1100
Time (t) = 2 years
$\text{Rate}=\frac{\text{S.I.}\times100}{\text{P}\times\text{r}}$
$=\frac{1100\times100}{8250\times2}$
$=\frac{20}{3}\%=6\frac23\%\text{ p.a.}$
