Question

the value of a car depreciate 20% every year if after 2 years the price of a car is 420000 find the original price of the car ​

Answer 1

Answer:

656250 RS.

Step-by-step explanation:

take 1%= x

100%= 100x

100x = cost of the car before two years

so after 1 year it will depreciate by 20%

so,

100%-20%=80%

80% of 100 x

(80/100 )* 100x

=80x

after 2 years

80%of 80x

(80/100)*80x

=64x

so,64x=420000

x=420000/64

= 6562.5 RS.

1%=x

1% of cost of the car before two years = 6562.5 RS.

100%= 100x

100x=6562.5 RS × 100

= RS.656250

answer:

656250 RS.
