Since the rate is already 'per month' and time is in 'months', directly multiply principal, rate, and time, then divide by 100. Calculation: 700×0.07×9=7×7×9=441.
Principal P = ₹700, Rate of interest R = 7% per month, Time T = 9 months
SI=100P×R×T
Since the rate is already 'per month' and time is in 'months', directly multiply principal, rate, and time, then divide by 100. Calculation: 700×0.07×9=7×7×9=441.
Students often mistakenly divide the time by 12 (converting to years) or the rate by 12, even though the rate is already explicitly given as 'per month'.
Identify given values
The principal P is ₹700, the rate R is 7% per month, and the time T is 9 months.
P=700,R=7,T=9
Apply Simple Interest formula
The formula for simple interest is SI=100P×R×T. Since the time units and rate units are compatible (both in months), no conversion is needed.
SI=100700×7×9
Calculate the result
Simplify the expression: SI=7×7×9=49×9=441.
SI=441
D is correct because the simple interest calculated for 9 months is ₹441.
Always check if the rate unit (e.g., annual, monthly, quarterly) matches the time period unit before applying financial formulas to avoid unnecessary division or multiplication factors.
