Answer 1

Answer:

₹18, 952.5

Step-by-step explanation:

We can use two methods:

1. Compound Interest equation

2. Calculation

I give you the both.

1. CI Equation

A = P {1 + (r/100)}ⁿ

Here P = current price of the TV = ₹21000

r = -5% ; n = 2 years ; A = to be calculated

A = ₹21000{1-(5/100)}²

= ₹21000*{ 1-(1/20) }² = ₹21000* 19²/20²

= ₹21000*361/400 = ₹ (52.5 *361)

= ₹18,952.5

2. Calculation

The price of the TV after 1 year

= ₹21000- {(5/100)*21000}

= ₹21000- ₹1050

= ₹19950

The price of the TV after 2 years

= ₹19950-{(5/100)*19950}

= ₹19950- 997.5

= ₹18, 952.5
