A new car costs Rs. 360000.Its price depreciates at the rate of 10% a year during the first two years and at the rate of 20% a year thereafter.What will be the price of the car after 3 years?

Explanation

Present cost of car = '360000'
Value of car after '1' year = '10% of 360000' => '10/100×360000'
=> '3600000 / 100' => '36000'
New price =360000-36000'
=> '324000'
Cost of car after '2 'year = '10% of 324000'
Cost of car after 3 year = 20% of '291600 '=> '20/100×291600'
=> '20×2916'
=> '58320' New price = '291600 - 58320'
=233280
