A washing machine is available for Rs. 13,500 cash or Rs. 6,500 as cash down

payment followed by three monthly instalments of Rs. 2,500 each. Find the rate of

interest charged under instalment plan.

In Solving this question

Cash price of washing machine = Rs. 135000Cash down payment = Rs. 6500Balance due = Rs(13500 – 6500) = rs. 7000No. of equal instalments = 3Amountof each instalment =rs. 2500Amount paid in installment = Rs. 7500Therefore, interest paid in installment scheme = rs(7500-7000) = rs. 500Principal for the 1^{st}month = Rs. 7000Principal for the 2^{nd}month = Rs. 4500Principal for the 3^{rd}month = Rs. 2000Total = Rs. 13500Let the rate of interest be r% per annumI = p*r*1 / 1200Then, I = 13500*r*1 / 100*12=> 500 =13500*r*1 / 100*12=>r = 500*12/ 135=>r = 44.4 %Why We Have Taken The Time As One Month
