Different techniques for solving Interest Related Math
Various (short) rules of solving mathematical problems: Basically, all problems can be solved by only two sources of interest. (a) i= 100. (b) P= C (1+rt/100) Here, I= Interest, C= Capital, r= rate of interest, t= time (in year) & P= Capital+Interest Details Formulas: Source: 1 When the value of money or real, time and interest rate is given: Interest or profit = (money x time x interest rate) / 100 অর্থাৎ, I=Crt/100, here, I= Interest, C= Capital, r= rate of interest, t= time (in year) Question: what is the interest of 500 % of 3 years in simple interest? Solution: 100 = 100, interest / profit = (500 x 3 x 10) / 100 = 150 = 150 tk Question: what will be the rate of 5 years per cent per year? Solution: In the same way, i=crt / 100 Or, R= (I x 100)/ (c x to) Interest Rate = (140 x 100) / (400 x 5) = 7 TAKA Question: how much money will be rs. 4 per cent per cent per cent per cent? Solution: In the same way, i=crt / 100, or, = (100 x) / (100 x) / (100 x) Good, capital = (84 x 10...
