Question

Ahmed paid $34 000 for a car.His car decreased in value by 40% at the end of the first year.The value at the end of the second year was 10% less than the value at the end of the first year.Calculate the value of Ahmed’s car after 2 years.

Answer 1

Answer:

first step:

40% of 34 000

40/100 * 34 000 = 13 600

subtract : 34000 - 13 600 = 20 400

second step:

10% of 20 400

10/100 * 20 400 = 2040

subtract : 20 400 - 2040 = $ 18 360

final answer = $ 18360

Answer 2

Answer:

Cost of car=$34000

1percent=34000÷100

=340

Value decreased at the end of 1st year

= 40%

34000-40%

= 40×340

= 13600

Value left of car at the end of first car =

34000-13600=$20400

1 percent of $20400=

20400÷100 =204

Percent decreased in 2nd year =10%

10×204=2040

Value of car left in the end of the 2nd year = 20400-2040

=$18360
