Answer 2

Option 'b' is correct.

Step-by-step explanation:

Since we have given that

Present cost of the car = 1000000

Depreciate = 25% in the first year, 20% in the second year, 15% in the third year.

So, the price of the car after 3 years would be

$1000000\times (1-\dfrac{25}{100})(1-\dfrac{20}{100})(1-\dfrac{15}{100})\\\\=1000000\times (1-\dfrac{1}{4})(1-\dfrac{1}{5})(1-\dfrac{3}{20})\\\\=1000000\times \dfrac{3}{4}\times \dfrac{4}{5}\times \dfrac{17}{20}\\\\=510000$

Hence, Option 'b' is correct.
