ML Aggarwal Solutions for Class 8 Maths Chapter 8 Simple And Compound Interest

The interest, typically expressed as a percentage, can be either simple or compounded. Simple interest is based on the principal amount of a loan or deposit. Interest is the cost of borrowing money, where the borrower pays a fee to the owner for using the owner's money. The interest is typically expressed as a percentage and can be either simple or compounded. In contrast, compound interest is based on the principal amount and the interest that accumulates on it in every period. Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate raised to the number of compound periods minus one. Interest can be compounded on any given frequency schedule, from continuous to daily to annually.


Simple and compound interest is used; Loans such as instalments loans, auto loans, educational loans, and mortgages use simple interest. The compound interest is used by most of the savings account as it pays the interest.


The simple interest formula is I = P x R x T. Compute compound interest using the following formula: A = P(1 + r/n) ^ nt. Assume the amount borrowed, P, is $10,000. The annual interest rate, r, is 0.05, and the number of times interest is compounded in a year, n, is 4.
