Solution
1. The total number of employees of direct-recruit Clerk, Officer Scale I and Officer Scale II:
= {8000*(10+15+30)}/100=80*55= 4400
2. The difference between promotee officer scale II and direct-recruit clerk:
= {(8000*30%)*40%} – {(8000*10%)*30%}
= 960-240
= 720
3. Promotee in Officer Scale II= {(8000*30%)*40%}=960
Direct-recruits in Officer Scale III= {(8000*20%)*40%}=640
Required Percentage= (960/640)*100= 150%
4. Total number of employees in direct-recruit Officer Scale I and promotee Officer Scale IV:
= {(8000*15%)*100%} + {(8000*25%)*80%}
= 1200+1600
= 2800
5. Total number of direct-recruit Officer III={(8000*20%)*40%}=640
