Solution & Step-by-Step Answer:
Property value = ₹ 8,00,000 Policy value = 75% × 8,00,000 = ₹ 6,00,000 ∵ Rate of Premium = 0.80% ∴ Amount of Premium = 0.80% × 6,00,000 = ₹ 4,800 ∵ Rate of commission = 9% ∴ Agent commission = 9% × 4800 = ₹ 432

Solution & Step-by-Step Answer:
Down payment = ₹ 20,000 ∵ n = 2 years But, EMI Payable monthly ∴ n = 2 × 12 = 24 ∵ r = 12% p.a. compounded monthly ∴ P = 1,00,00 × 0.2120 ∴ P = ₹ 21,200 Cash price = Present value + Down payment = 21,200 + 20,000 = ₹ 41,200

Question 19
Maharashtra Board Solution
Find the present value of an annuity immediate of ₹ 20,000 per annum for 3 years at 10% p.a. compounded annually. [Given: (1.1)-3 = 0.7513]
Solution & Step-by-Step Answer:
∵ C = ₹ 20,000 ∵ n = 3 years ∵ r = 10% p.a. ∴ P = 2,00,000 [1 – 0.7513] ∴ P = 2,00,000 [0.2487] ∴ P = ₹ 49,740

Question 20
Maharashtra Board Solution
A man borrowed some money and paid it back in 3 equal installments of ₹ 2,160 each. What amount did he borrow if the rate of interest was 20% per annum compounded annually? Also, find the total interest charged. [Given: (1.2)-3 = 0.5788]
Solution & Step-by-Step Answer:
∵ C = ₹ 2,160 ∵ n = 3 ∵ r = 20% p.a. ∴ P = ₹ 6,251.04 ∴ Total amount paid = 2,160 × 3 = ₹ 6,480 ∴ Interest = 6,480 – 6,251.04 = ₹ 228.96

Solution & Step-by-Step Answer:
∵ A = ₹ 9,28,200 ∵ n = 4 years ∵ r = 10% p.a. ∴ 9,28,200 × 0.1 = C[1.4641 – 1] ∴ 92,820 = C × 0.4641 ∴ = C ∴ C = ₹ 2,00,000

Question 22
Maharashtra Board Solution
Find the future value after 2 years if an amount of ₹ 12,000 is invested at the end of every half-year at 12% p.a. compounded half-yearly. [Given: (1.06)4 = 1.2625]
Solution & Step-by-Step Answer:
∵ n = 2 years Payable half yearly, n = 2 × 2 = 4 ∵ C = ₹ 12,000 ∵ r = 12% p.a. Compounded half yearly ∴ A = 1,00,000 [1.2625 – 1] ∴ A = 1,00,000 × 0.2625 ∴ A = ₹ 26,250


Question 23
Maharashtra Board Solution
After how many years would an annuity due of ₹ 3,000 p.a. accumulated ₹ 19,324.80 at 20% p.a. compounded annually? [Given: (1.2)4 = 2.0736]
Solution & Step-by-Step Answer:
∵ C = ₹ 3,000 ∵ A = ₹ 9,324.80 ∵ r = 20% p.a. ∴ 19,324.80 = 15,000 × 1.2[(1.2)n – 1] ∴ 19,324.80 = 18,000[(1.2)n – 1] ∴ + 1 = (1.2)n ∴ 1.0736 + 1 = (1.2)n ∴ 2.0736 = (1.2)n ∴ (1.2)4 = (1.2)n ∴ n = 4 years

Question 24
Maharashtra Board Solution
Some machinery is expected to cost 25% more over its present cost of ₹ 6,96,000 after 20 yeas. The scrap value of the machinery will realize ₹ 1,50,000. What amount should be set aside at the end of every year at 5% p.a. compound interest for 20 years to replace the machinery? [Given: (1.05)20 = 2655]
Solution & Step-by-Step Answer:
Present cost = ₹ 6,96,000 Expected cost = 25% × 6,96,000 + 6,96,000 = 1,74,000 + 6,96,000 = ₹ 8,70,000 ∴ Scrap value = ₹ 1,50,000 ∴ Sinking fund = 8,70,000 – 1,50,000 = ₹ 7,20,000 ∴ A = ₹ 7,20,000, n = 20 years, r = 5% p.a. ∴ 7,20,000 × 0.05 = C[(1.05)20 – 1] ∴ 36,000 = C[2.655 – 1] ∴ 36,000 = C × 1.655 ∴ = C ∴ C = ₹ 21,752.27
