Solution

Present value of annuity due, P = `(a (1 + i))/i [1 - 1/(1 + i)^n]`

Here a = 1500, n = 16, i = `8/100` = 0.08

P = `(1500 (1 + 0.08))/(8/100) [1 - 1/(1.08)^16]`

= `(1500 xx 100 xx (1.08))/8 [1 - 1/3.172]`      ...[∵ (1.08)16 = 3.172]

= `162000/8 [1 - 1/3.172]`

= `20250 [1 - 0.31524]`

= 20250 [0.68476]

= 13866.39
