# Solving Simple Interest Problems Say, when compounded annually for 2 years, the principal amount with interest accrued at the end of first year becomes the principal for the second year. SI = PTR / 100 → R = SI * 100 / PT R = 2250 * 100 / 25000 * 3 → R = 3%. Let us work on some examples to understand the concepts and the differences. Before starting the formula for the simple interest, let us first state some terms that we will use in the formula. In some cases the days of the start and the days when we calculate the interest are present. Then the total simple interest that Khan pays is the sum of the interests.

Then, T = 100*30/100*15 = 2% A money lender lent Rs.

The amount should be returned to him when the total interest comes to Rs.

Now let us solve some examples to get acquainted with these formulae. 68,000 at 16(2/3)% per annum for a period of 9 months?

Example 5: A man took a loan from a bank at the rate of 12 % p.a.

Simple Interest is the rate at which we lend or borrow money.

In the following section, we will define the important terms and formulae that will help us solve and understand the questions on the simple interest. Interest: This is the extra money paid for taking the money as loan. Simple Interest = Principal * Time * Rate of interest / 100 Abbreviated as SI = PTR/100 In compound interest, the principal amount with interest after the first unit of time becomes the principal for the next unit. 27250 at the end of 3 years when calculated at simple interest. : Simple interest = 27250 – 25000 = 2250 Time = 3 years. 10 and at the end of the year, the amount to be paid is Rs. Time: This is the time period for which the money is lent or the time period in which the money has to be returned with interest. The difference between SI and CI compounded annually on a certain sum of money for 2 years at 8% per annum is Rs. – x → 104x/625 Therefore, 104x/625 – 4x/25 = 12.80 Solving which gives x, Principal = Rs. 7000 Answer: Let x, y and z be the amounts that Khan invests in schemes A, B and C respectively. Also, we have the conditions that 10x 12y 15z = Rs. Combining the above equations, we have: 16y 12y 36y = Rs.
