1) The interest on rs.750 at 3 paise per month for 6 months is Rs. 135.
2) The interest on rs.225 at 3/2 paise per month for 8 months is Rs. 27.
Step-by-step explanation:
Question (1):
Principal, P = Rs. 750
Time period, T = 6 months
Rate of interest, R = 3 paise per rupee per month = [3/100] per month = 3% per month
Thus,
The interest for 6 months at a rate of 3% per month on Rs. 750 will be given by
= [PRT]/100
= [750 * 3 * 6] / 100
= Rs. 135
Question 2:
Principal, P = Rs. 225
Time period, T = 8 months
Rate of interest, R = 3/2 paise per rupee per month = [1.5/100] per month = 1.5% per month
Thus,
The interest for 8 months at a rate of 1.5% per month on Rs. 225 will be given by
= [PRT]/100
= [225 * 1.5 * 8] / 100
= Rs. 27
