A 1325

B 1195

C 1265

D 1235

ANS:B - 1195

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.
