3. 

For which of the following categories the percentage increase in the number of employees working in the Company from 1995 to 2000 was the maximum?

[A]. Managers
[B]. Technicians
[C]. Operators
[D]. Accountants

Answer: Option A

Explanation:

Number of Managers working in the Company:

In 1995 = 760.
In 2000 = (760 + 280 + 179 + 148 + 160 + 193) - (120 + 92 + 88 + 72 + 96)
= 1252.

Therefore Percentage increase in the number of Managers

    = [ (1252 - 760) x 100 ] % = 64.74%.
760

Number of Technicians working in the Company:

In 1995 = 1200.
In 2000 = (1200 + 272 + 240 + 236 + 256 + 288) -

   (120 + 128 + 96 + 100 + 112)
= 1936.

Therefore Percentage increase in the number of Technicians

    = [ (1936 - 1200) x 100 ] % = 61.33%.
1200

Number of Operators working in the Company:

In 1995 = 880.
In 2000 = (880 + 256 + 240 + 208 + 192 + 248) -

    (104 + 120 + 100 + 112 + 144)
= 1444.

Therefore Percentage increase in the number of Operators

    = [ (1444 - 880) x 100 ] % = 64.09%.
880

Number of Accountants working in the Company:

In 1995 = 1160.
In 2000 = (1160 + 200 + 224 + 248 + 272 + 260) -

    (100 + 104 + 96 + 88 + 92)
= 1884.

Therefore Percentage increase in the number of Accountants

    = [ (1884 - 1160) x 100 ] % = 62.41%.
1160

Number of Peons working in the Company:

In 1995 = 820.
In 2000 = (820 + 184 + 152 + 196 + 224 + 200) -

    (96 + 88 + 80 + 120 + 104)
= 1288.

Therefore Percentage increase in the number of Peons

    = [ (1288 - 820) x 100 ] % = 57.07%.
820

Clearly, the percentage increase is maximum in case of Managers.

"Which of the following categories has the highest percentage increase from its numbers in 1995 to its total number in 2000?"

Rephrase the original question. It's a run on sentence.

I think this ques shud be ask for 10 marks in CBSE...rather than for 1 mark in CAT :)

Why dividing by left people value rather than total members?

Is there any shortcut for this question?

Explain it clearly.

Veiru said: (Feb 15, 2018)  
I am not understanding this problem.

Why are they subtracting the total employees for all the years from the year 1999 and why the employees for 1999 is taken as the base.

(like manager 1252-760÷760).

Can somebody please explain it clearly?

For the % calculation there's one formula
( Final value - initial value)/ initial value*100
