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

Answer 1

The correct option is 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 $1997$
$=\frac{1}{5}\times (1007+1464+1152+1380+972)$
$=\frac{1}{5}\times \left(5975\right)$
$=1195$.
