उत्तर

Given a = ₹ 3000, i = 0.05, n = 4

P = `"a"/"i" [1 - (1 + "i")^(-"n")]`

= `3000/0.05 [1 - (1 + 0.05)^(-4)]`

= `3000/0.05 [1 - (1.05)^(-4)]`

= 60,000 [1 − 0.8227] .......[∵ (1.05)–4 = 0.8227]

= 60,000 (0.1773)

= ₹ 10,638

Given that the cash down payment is ₹ 5000

∴ Cash down price of the equipment = 5000 + 10,638 = ₹ 15,638
