Question

Demand of a car went down by 25% in 2016 and 20% in 2017 what is the net% decrease in demand?

Answer 1

-25 -20 + 500/100
-25-20+5 = 40% decreased
Or

If demand of cars 100 then 25% less = 75
Now 20 % less = 75*80/100 = 60
We can say demand 40 % decreased

Answer 2

Answer:

40% is the correct answer.

Given:

The demand for a car went down by 25% in 2016 and 20% in 2017

To find:

the net% decrease in demand

Solution:

let the initial demand for the car be 100.

in 2016,

the demand went down by 25 %

so, demand in 2016 = 100 - [25/ 100 x 100]

demand in 2016 = 100- 25 = 75

now, in 2017,

demand in 2017= demand in 2016 - 20% demand in 2016

demand in 2017= 75 - [20/100 x 75]

demand in 2017 = 75-15 = 60

so, the demand went from 100 to 60.

so, change = [100-60 / 100] x 100

so, net decrease = 40 %

Hence, 40% is the correct answer.
