Answer 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

= 1/5x (5975) = 1195.
