उत्तर

The cost of the new computer = ₹ 100000

The depreciation rate = 50% per annum

Time period (T) = 2 years

Let the cost of computer after 2 years = ₹ A

∵ `A = P(1 - R/100)^T`

= `100000(1 - 50/100)^2`

⇒ `A = 100000 xx 1/2 xx 1/2`

= 25000 × 1

∴ A = ₹ 25000

Hence, the cost of computer after 2 years is ₹ 25000.
