Find the rate ofinterest charged under instalment plan.In Solving this questionCash 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 1stmonth = Rs. 7000Principal for the 2ndmonth = Rs. 4500Principal for the 3rdmonth = 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
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. 135000
Cash down payment = Rs. 6500
Balance due = Rs(13500 – 6500) = rs. 7000
No. of equal instalments = 3
Amountof each instalment =rs. 2500
Amount paid in installment = Rs. 7500
Therefore, interest paid in installment scheme = rs(7500-7000) = rs. 500
Principal for the 1stmonth = Rs. 7000
Principal for the 2ndmonth = Rs. 4500
Principal for the 3rdmonth = Rs. 2000
Total = Rs. 13500
Let the rate of interest be r% per annum
I = p*r*1 / 1200
Then, I = 13500*r*1 / 100*12
=> 500 =13500*r*1 / 100*12
=>r = 500*12/ 135
=>r = 44.4 %
