Finding Time when Principal and Rate are givenIn this section you will learn finding time when principal and rate are given in easy way. The time period may be in years, days or in months. For everyone we have different formulas.When time in years S.I x 100 Time = T =  P x R When time in days S.I x 100 x 365 Time = T =  P x R When time in months S.I x 100 x 12 Time = T =  P x R Examples : 1) Principal = P = $3500, S.I = $700 and rate = R = 5%. Find the time period in years. Solution : S.I x 100 Time = T =  P x R 700 x 100 Time = T =  3500 x 5 70,000 Time = T =  17,500 Time = 4 years. ________________________________________________________________ 2) Principal = P = $4800, S.I = $900 and rate = R = 7.5%. Find the time period in months. Solution : S.I x 100 Time = T =  P x R 900 x 100 x 12 Time = T =  4800 x 7.5 1,080,000 Time = T =  36000 Time = 30 months. ________________________________________________________________ 3) Principal = P = $7300, S.I = $500 and rate = R = 4%. Find the time period in days. Solution :
