उत्तर
Since, the machinery is expected to cost 25% more over its present cost i.e., 6,96,000,
∴ Expected value of machinery
= Present cost + 25% of present cost
= `6,96,000 + 25/100 xx 6,96,000`
= 6,96,000 + 1,74,000
= ₹8,70,000
After 20 years, scrap value of the machinery is ₹ 1,50,000.
∴ Accumulated value of machinery = Expected value of machinery – Scrap value of machinery
= 8,70,000 – 1,50,000
= ₹7,20,000
∴ A = ₹ 7,20,000
Also, r = 5% p.a., n = 20 years,
i = `"r"/(100) = (5)/(100)` = 0.05
Since, A = `"C"/"i"[(1 + "i")^"n"` - 1]
∴ 7,20,000 = `"C"/(0.05)[(1 + 0.05)^20 - 1]`
∴ 7,20,000 x 0.05 - C[(1.05)20 – 1]
∴ 36,000 = C (2.653 – 1)
∴ 36,000 = C x 1.653
∴ C = `(36,000)/(1.653)`
∴ C = ₹21,778.58
∴ Sum of ₹21,778.58 should be set aside at the end of each year.

[Given (1.1)4 = 1.4641]
For an annuity due, C = ₹ 2000, rate = 16% p.a. compounded quarterly for 1 year
∴ Rate of interest per quarter = `square/4` = 4
⇒ r = 4%
⇒ i = `square/100 = 4/100` = 0.04
n = Number of quarters
= 4 × 1
= `square`
⇒ P' = `(C(1 + i))/i [1 - (1 + i)^-n]`
⇒ P' = `(square(1 + square))/0.04 [1 - (square + 0.04)^-square]`
= `(2000(square))/square [1 - (square)^-4]`
= 50,000`(square)`[1 – 0.8548]
= ₹ 7,550.40
