Continuation...... A is equals to p + s i this is a formula which is to be applied whenever you have to find out the amount. If you carefully read the question once again in the question tell see that Ravi borrowed rupees 8000 from a bank at 8% of interest so we need to find amount he has to pee after 4.5 years so first we need to know what is the pay which is which is the principle principle is easy the money given or borrowed is the principal always we know that the principal is 8000 rupees now when we know the percentage and the year but we don't know the simple interest so first we need to find out the interest for that you have to apply the formula as a is equals to PTR divided by 100 then you can easily find out the amount
