The bar graph given below shows the percentage distribution of the total production of a car manufacturing company into various models over two years.

Percentage of Six different types of Cars manufactured by a Company over Two Years

5. 

For which model the percentage rise/fall in production from 2000 to 2001 was minimum?

[A]. Q
[B]. R
[C]. S
[D]. T

Answer: Option B

Explanation:

The percentage change (rise/fall) in production from 2000 to 2001 for various models is:

For P = [ (176000 - 105000) x 100 ] % = 67.62%, rise.
105000

For Q = [ (88000 - 52500) x 100 ] % = 67.62%, rise.
52500

For R = [ (70000 - 66000) x 100 ] % = 5.71%, fall.
70000

For S = [ (44000 - 35000) x 100 ] % = 25.71%, rise.
35000

For T = [ (52500 - 44000) x 100 ] % = 16.19%, fall.
52500

For U = [ (35000 - 22000) x 100 ] % = 37.14%, fall.
35000

Therefore Minimum percentage rise/fall is production is the case of model R.

Is there any shortcut for this problem?

Its take too much time please explain in short method.

Do not solve each and every question asked. What options are given try solving those only.

Eg: In this problem, Q,R,S,T given. So, solve only those not all.

Sometimes we are taking total no.of cars produced in 2000 as divisor and sometimes 2001 why?

Depending on Which criteria are we declaring it 'fail' or 'pass'?

It entirely depends on rise or fall and that is clear from the picture itself. As we are solving this question for rise or fall hence that term comes in then. With respect to which there is a rise or fall in the production.

Can we solve it by just observing the graph ? Any shortcut ?

We take previous year as divisor.

Not able to understand. Please explain it clearly.

350x = 440y find x/y almost equals 1.26 find respective ratio closer to 1.26 will be the answer check for given options for are x/y equals 1.33 for R 1.5.

Thanks @Neha.

Maximum is Q why it say that is R.

Not getting it. Please explain it clearly.

How did you calculate the percentage of change of P?

How did you calculate the percentage of P? Please explain in detail.

Ashwin said: (Mar 12, 2019)  
Can someone explain why we are dividing?

176000 from where it came? Please explain.
