Three persons are working between E and G and both works on even numbered floor. G works just above the person who gets 2lakh salary and just below the person who gets 10lakh salary. C works just above the person who gets 3lakh salary and just below the person who gets 2lakh salary. Here, we get two possibilities i.e. Case 1 and Case 2. There are as many floors between A and F as between F and B. D works above C and below H. 
There are as many persons work above D as below the person who gets 6lakh salary. Here, Case 1 is ruled out. A works above the person who gets 8lakh salary but not just above. The person who gets 11lakh salary works above the person who gets 4lakh salary and below the person who gets 5lakh salary. So, the final arrangement will be: –
