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.

What is the pooled average of the total number of employees of all categories in the year 1997?

A.	1325
B.	1195
C.	1265
D.	1235

Answer: Option B

Explanation:

Total number of employees of various categories working in the Company in 1997 are:

Managers = (760 + 280 + 179) - (120 + 92) = 1007.

Technicians = (1200 + 272 + 240) - (120 + 128) = 1464.

Operators = (880 + 256 + 240) - (104 + 120) = 1152.

Accountants = (1160 + 200 + 224) - (100 + 104) = 1380.

Peons = (820 + 184 + 152) - (96 + 88) = 972.

Therefore Pooled average of all the five categories of employees working in the Company in 1997

= 1 x (1007 + 1464 + 1152 + 1380 + 972)

5

= 1 x (5975)

5

= 1195.
