A person borrowed some amount from a bank at the rate of 4% per annum compounding yearly. he lent the whole amount to a shopkeeper at 6% per annum compound interest compounded half yearly . if at end of the year he gained Rs.104.50, find the amount that he borrowed from the bank.

5000 Rs

if borrowed is 100 compound interst is 104

therefore, interest to be paid is 4

if the shopkeeper got rs 100 then 6 months interest is 3 and next 3 months interest is 3.09 so interest to be paid is = 6.09

difference 6.09-4=2.09

if 2.09 is the difference principle is 100

if 104.50 is the difference the principle = (100x104.50)/2.09 =5000
