Given : Rs. 450 at 6% per annum from August 4 to October 16​.

To find : The simple interest ?

Solution :

Applying simple interest formula,

$SI=P\times R\times T$

Where, P is the principal P=Rs.450

R is the interest rate R=6%=0.06

T is the time from August 4 to October 16​ T=91 days

Convert into years,

$SI=6.73$

Therefore, the simple interest is Rs.6.73.
