उत्तर
Given, C = ₹3,000, A = ₹60,000, r = 10% p.a.
∴ i = `"r"/(100) = (10)/(100)` = 0.1
Since, A = `"C"/"i"[(1 + "i")^"n" - 1]`
∴ 60,000 = `(3,000)/(0.1)[(1 + 0.1)^"n" - 1]`
∴ `(60,000 xx 0.1)/(3,000)` = (1.1)n – 1
∴ 2 = (1.1)n – 1
∴ (1.1)n = 2 + 1
∴ (1.1)n = 3
It is given that (1.1)11 = 2.8531 and (1.1)12 = 3.1384
∴ n will be between 11 years and 12 years.
Thus, the least number of years for which an annuity of ₹3,000 per annum must run is 12 years.
