a sum of 390200 is to be paid back in 3 equal annual installments how much is each installments if rate is 4% per annum compounded annually

Why cant we do this in this manner?Let the principal 390200 be divided into 3 sums say P, Q R such that P+Q+R = 390200

Let an instalment of Rs I be paid after 1 year to clear a principal of P therefore

P*104 / 100 = I

Let an instalment of Rs I be paid after 2 years to clear a principal of Q therefore

Q * 104 * 104 /10000 = I

Let an instalment of Rs I be paid after 3 years to clear a principal of R therefore

R* 104 *104 *104 / 1000000 = I

so I *100/104 = P

I * 10000 /10816 = Q

I * 1000000 /1124864 = R so {(100 /104) + (10000 /10816) + (1000000 /1124864)} I = P+Q+R = 390200.

{(1081600 + 1040000 + 1000000 ) / 1124864 } I = 390200

(3121600 /1124864 )I = 390200

I = 1124864/8 = 140608

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
