the price is 120 rupees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "he pays 25 rupees down.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "he will then pay the rest in 4 monthly installments of 25 rupees each.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "take away the 25 rupees that he put down and the amount he still owes on the pressure cooker is 95 rupees.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this amount is paid off in 4 monthly installments of 25 rupees apiece.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the use of a financial calculator is indicated here.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "one such calculator can be found online at https://arachnoid.com/finance/https://arachnoid.com/finance/\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "your inputs to this calculator will be:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "present value = 95
\n" ); document.write( "future value = 0
\n" ); document.write( "number of time periods = 4
\n" ); document.write( "payment amount = -25
\n" ); document.write( "interest rate percent per time period = what you want to find.
\n" ); document.write( "payment made at the end of each time period.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the time periods are months, so your payment will be made at the end of each month.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the percent value is shown as positive because it's money that you borrowed to pay for the pressure cooker.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the payment is shown as negative because it's money that you spend in order to apy off the loan.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "once yo've made your inputs, you click on IR and the calculator tells you the interest rate percent per time period.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that interest rate percent will be equal to 2.083778 percent.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's the interest rate per momth.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the equivalent interest rate per year will be 12 * that which makes the annual percent interest rate equal to 25.005336 percent.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this can be rounded to approximately 25.01 percent.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this is what the calculator display looks like after you're done.\r
