@kushalkthakker56200 = 2x/(11/10) + 2x/(11/10)^2 + x/(11/10)^3solve to get x =13310

can anyone please help me on this.

A debt of Rs. 56200 is repaid in three annual payments. The first and the second payments are of equal amounts and the third payment is half that of the first. If the rate of interest is 10% per annum payable annually, find the third payment.

answer is 13310.

my approach was

let first installment be 2x ,second 2x and third x

present value of the loan = (56200*3*10)/100

int on first installment = (2x*2*10)/100

int on second installment = (2x*1*10)/100

the equation which i formed goes like

present value - interest on first installment - interest on second installment = 5x

doing so i am not getting the exact answer there seems to be some falw in my reasoning can some one help me identify it? thanks!! :)
