उत्तर

₹ 12500

Explanation;

Hint:

Cost of machine = 18000

Depreciation rate = `16 2/3 % = 50/3 %` p.a

Time period = 2 years

∴ As per depreciation formula,

Depriciated value = Original value `(1 - "r"/100)^"n"`

Substituting in above formula, we get

Depreciated value after 2 years

= `18000(1 - (50/3)/100)^2`

= `18000(1 - 50/(100 xx 3))^2`

= `18000(1 - 1/6)^2`

= `1800 xx (5/6)^2`

= `18000 xx 5/6 xx 5/6`

= ₹ 12,500
