={(8000*10%)*30%}+{(8000*15%)*100%}+{(8000*30%)*60%} =240+1200+1440 =2880

2. The difference between promotee officer scale II and direct-recruit clerk:
= {(8000*30%)*40%} – {(8000*10%)*30%}

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:
