e)

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

= 1/5x (1007 + 1464 + 1152 + 1380 + 972)

= 1 /5x (5975)

= 1195

3) During the period between 1995 and 2000, the total number of operators who left the Company is what percent of the total number of operators who joined the Company?

a) 19%

d)

Total number of Operators who left the Company during 1995 – 2000

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

= 580.

Total number of Operators who joined the Company during 1995 – 2000

= (880 + 256 + 240 + 208 + 192 + 248)

= 2024.

Therefore Required Percentage = ( 580 x 100 ) % = 28.66% ~= 29%.

4) 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

e) None of these

a)

Number of managers working in 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) /760x 100 % = 64.74%. 

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) /1200 x 100 % = 61.33%.

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)/880 x 100 % = 64.09%.

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)/1160 x 100 % = 62.41%.

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