उत्तर

Given, C = ₹3,000, A' = 19324.80, r = 20% p.a.

∴ i = `"r"/(100) = (20)/(100)` = 0.2

Since, A' = `("C"(1 + "i"))/"i" [(1 + "i")^"n" - 1]`

∴ 19,324.80 = `(3,000(1 + 0.2))/(0.2) [(1 + 0.2)^"n" - 1]`

∴ 19,324.80 = `(3,000 xx 1.2)/(0.2) [(1.2)^"n" - 1]`

∴ 19,324.80 = 3,000 x 6 [(1.2)n – 1]

∴ `(19,324.80)/(18,000)` = (1.2)n  – 1

∴ `(19,32,480)/(18,000 xx 100)` = (1.2)n  – 1

∴ `(1,07,360)/(1,00,000)` = (1.2)n  – 1

∴ 1.0736 = (1.2)n  – 1
∴ (1.2) = 1.0736 + 1
∴ (1.2) = 2.0736
∴ (1.2) = (1.2)4       ...[ `Theta` (1.2)4 = 2.0736]
∴ n = 4 years
∴ After 4 years, an annuity due of ₹3,000 p.a. would accumulate to ₹19,324.80 at 20% p.a. compounded annually.

Find the amount of an ordinary annuity if a payment of ₹ 500 is made at the end of every quarter for 5 years at the rate of 12% per annum compounded quarterly. [Given (1.03)20 = 1.8061]


The future amount, A = ₹ 10,00,000

Period, n = 20, r = 5%, (1.025)20 = 1.675

A = `"C"/"I" [(1 + "i")^"n" - 1]`

I = `5/200` = `square` as interest is calculated semi-annually

A = 10,00,000 = `"C"/"I" [(1 + "i")^"n" - 1]`

10,00,000 = `"C"/0.025 [(1 + 0.025)^square - 1]`

= `"C"/0.025 [1.675 - 1]`

10,00,000 = `("C" xx 0.675)/0.025`

C = ₹ `square`
