solve from question 1-13

(i) What is the SI on Rs. 7500/ at the rate of 12% per annum for 8 years? (ii) A man borrowed Rs 15000% at the rate of 24%SI and to clear the debt after 6years, how much he has to return (iii) A man has to pay Rs 1500 as interest after 3 years at the rate of 10%. What amount he has taken? A sum of money at simple interest amounts to Rs. 875 in 3.5 years and to Rs. 900 in 4 years. The sum is interest rate,an amount of Rs. 27,000. Rate of interest for scheme P \& Q were 5% p.a. and 15\% p.a. respectively. If the total amount of simple interest earned in 4 years be Rs. 12600 , what was the amount invested in Scheme P? A money-lender claims he lends money at simple rate of interest of 10\% per annum. But he cleverly tricks the farmers by including the interest amount in the principal when he calculates it every six months. The effective annual rate of interest he is charging is: The sum of interest on a sum of money is 1/4 of the principal, and the number of years is equal to the rate of interest. What will be the rate percent? \begin{tabular}{|c|c|} \hline 6 & \begin{tabular}{l} The rate of interest for 2 years is 3%,4 years is 6%, and for \\ another 4 years is 4%.If a man gets interest of Rs. 3800 for 8 \\ years, Calculate the principal amount. \end{tabular} \\ \hline 7 & \begin{tabular}{l} years, Calculate the principal amount. \\ A sum of money becomes 5 times in 30 years.
