Calculation of Balance Amount with Interest
The amount paid at the time of purchase = Rs. 200000
Balance amount = Rs. 300000 - Rs. 200000 = Rs. 100000
Interest rate = 12% p.a. compounded half-yearly
Number of instalments = 20
Time period = 20 x 6 months = 10 years
Using the formula for compound interest, the balance amount with interest can be calculated as:
Balance amount with interest = P(1 + r/n)^(nt)
where P = principal amount, r = rate of interest, n = number of times interest is compounded in a year, and t = time period in years
Here, P = Rs. 100000, r = 12%/2 = 6% per half-year, n = 2 (compounded half-yearly), and t = 10 years
Balance amount with interest = 100000(1 + 0.06/2)^(2 x 10)
= Rs. 311922.22
Calculation of Instalment Amount
The instalments are to be paid in 20 equal half-yearly instalments. The first instalment is paid after 6 months from the date of purchase. Therefore, the total time period for the instalments is 20 x 6 months = 10 years.
The instalment amount can be calculated using the formula for the present value of an annuity:
Present value of an annuity = (C/r)(1 - 1/(1+r)^n)
where C = instalment amount, r = rate of interest per half-year, n = number of instalments
Here, the present value of the annuity is equal to the balance amount with interest, which is Rs. 311922.22. Therefore,
311922.22 = (C/0.06)(1 - 1/(1+0.06)^20)
C = 311922.22 x 0.06 / (1 - 1/1.06^20)
C = Rs. 8719.66
Therefore, the amount of each instalment is Rs. 8719.66 (Option A).
