Answer
1. ANSWER : D
Explanation - Required difference
= (272 + 240 + 236 + 256 + 288) - (200 + 224 + 248 + 272 + 260)
= 88.
2. ANSWER : B
Explanation - Total number of Peons working in the Company in 1999
= (820 + 184 + 152 + 196 + 224) - (96 + 88 + 80 + 120)
= 1192.
3. ANSWER : 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
= %= 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
= % = 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
= % = 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
= % = 62.14%
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
= % = 57.07%
Clearly, the percentage increase is maximum in case of Managers.
4. ANSWER : 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 = 1/5 x (1007 + 1464 + 1152 + 1380 + 972)
= 1/5 x (5975)
= 1195.
5. ANSWER : D
Explanation - 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
= (580/2024)x100% = 28.66% ~= 29%.
