You can put this solution on YOUR website!
the price is 120 rupees.

he pays 25 rupees down.

he will then pay the rest in 4 monthly installments of 25 rupees each.

take away the 25 rupees that he put down and the amount he still owes on the pressure cooker is 95 rupees.

this amount is paid off in 4 monthly installments of 25 rupees apiece.

the use of a financial calculator is indicated here.

one such calculator can be found online at https://arachnoid.com/finance/https://arachnoid.com/finance/

your inputs to this calculator will be:

present value = 95
future value = 0
number of time periods = 4
payment amount = -25
interest rate percent per time period = what you want to find.
payment made at the end of each time period.

the time periods are months, so your payment will be made at the end of each month.

the percent value is shown as positive because it's money that you borrowed to pay for the pressure cooker.

the payment is shown as negative because it's money that you spend in order to apy off the loan.

once yo've made your inputs, you click on IR and the calculator tells you the interest rate percent per time period.

that interest rate percent will be equal to 2.083778 percent.

that's the interest rate per momth.

the equivalent interest rate per year will be 12 * that which makes the annual percent interest rate equal to 25.005336 percent.

this can be rounded to approximately 25.01 percent.

this is what the calculator display looks like after you're done.
