उत्तर
Principal for the month of April = Rs. 0
Principal for the month of May = Rs. 4650
Principal for the month of June = Rs. 4750
Principal for the month of July = Rs. 8950
Total Principal for one month = Rs. 18,350
Time = `1/12` year, Rate = 4 %
Interest earned = `(18350 xx 1 xx 4)/(100 xx 12) = 61.17`
Money received on closing the account on 1st August, 2010
= Last Balance + Interest earned
= Rs. (8950 + 61.17)
= Rs. 9011.17
