Principal for the month of Feb = 
4500
Principal for the month of March = 4500
Principal for the month of April = 4500
Principal for the month of May = 6730
Principal for the month of June = 1730
Principal for the month of July = 7730
Total Principal for 1 month
= (4500+4500+4500+6730+1730+7730) = 29690
P = 29690, T = 
years, R = 6%
