Dear Student,


For the 1st half year:Principal, P = Rs. 12000Rate of Interest,R = 10% p.a.Time, T = 12 yearWe know, Interest, I = P×R×T100 and Amount = P + ITherefore, Interest = 12000×10×1100×2 = Rs. 600and Amount= 12000 + 600 = Rs. 12600She, repays Rs. 4000For, 2nd half year:P = Rs. 12600 - 4000 = Rs. 8600R =10%T = 12 yearTherefore, Interest = 8600×10×1100×2 = Rs. 430Amount = 8600 + 430 = Rs. 9030She repays Rs. 4000For the 3rd half year:P = Rs. 9030 - 4000 = Rs. 5030R =10%T = 12 yearTherefore, Interest = 5030×10×1100×2 = Rs. 251.50Amount = 5030 + 251.50 = Rs. 5281.50So, Rachan must repay Rs. 5281.50 at the end of 18 months to clear the loan.
