If h receives Rs. 198 as interest on 1st January, 2007, Find the rate of interest paid by the bank.

#### Solution

Principle for the month of Jan = Rs. 3,580
Principle for the month of Feb = Rs. 3,580
Principle for the month of march = Rs. 1,580
Principle for the month of April = Rs. 7,780
Principle for the month of May = Rs. 7,780
Principle for the month of June = Rs. 3,280
Principle for the month of July = Rs. 3,280
Principle for the month of Aug = Rs. 5,910
Principle for the month of Sept = Rs. 5,910
Principle for the month of Oct = Rs. 2,690
Principle for the month of Nov = Rs. 4,190
Principle for the month of Dec = Rs. 3,240
Total Equivalent principle for 1 month = Rs. 52,800

∴ Rate% = (I xx100) /(PxxT) % = (198xx100xx12)/(52,800xx1) %= 4.5%
