Option 2 : Rs. 4,500

Let the cash down payment be Rs. X

The amount as per the compound interest can be given as

A = P (1 + R/100)t

Where A = Amount

P = Principal

R = Rate of interest

t = Time period

As the cost price of television is Rs. 13240

∴ We can write

13240 = X + (2794/1.1) + (6292/1.12) + (1331/1.13)

As the 2794 is paid after one year hence t = 1 and as 6292 is paid after 2 years hence t = 2 and so on.

∴ 13240 = X + 2540 + 5200 + 1000

∴ X = 4500
