Find Simple Interest ( SI ) when time is given in months
Simple interest – Find Simple Interest ( SI ) when time is given in months
Question : –
Find the Simple Interest ( SI ) on ₹ 1000 at 6 % per annum for 9 months ?
Explanation : –
We know that
SI =
Where,
P = Principal in Rs.
R = Rate ( In percentage per annum or percentage per month )
T = Time ( In Years, if Rate is given in Years or months, if Rate is given per month )
We are given that
P = ₹ 1000
R = 6% p.a.
T = 9 months
Since the rate of interest has been given on a yearly basis, we need to convert the time into Years
T = years
T = years
We know that,
SI =
SI = ₹ [ 1000 x 6 x x ]
SI = ₹ 45
Hence, SI = ₹ 45
