Problems on Simple Interest: 1. Jimmy borrowed some money at the rate of 3% p.a. for the 1 st 5 years, 5% p.a. for the next 7 years and 8% p.a. for the period beyond 15 years. If the total interest paid by him at the end of 15 years is 2220, how much money did he borrow? Solution:                  P*5*3/100 + P*7*5/100 + P*3*8/100 = 2220                  P/100 [15+35+24] = 2220                  P = 100*2220/74                  P = 3000.   2. A financier claims to be lending money at simple interest, but he includes the interest every six months for calculating the principal. If he’s charging an interest of 20%, the effective rate of interest becomes: Solution:                  Let the sum be 100.                  S.I for the 1 st 6 months = 100*1/2*20/100 = 10.                  S.I for the 1 st 6 months = 110*1/2*20/100 = 11.                  The amount at the end of 1 year = 100+10+11 = 121.                                     Eff
