Question
Four of the following five are alike in certain way and
hence form a group, find the one which does not belong to that group? Read the following information carefully to answer the questions given below. Eight persons are working on different floors in an eight floored building. Bottommost floor is numbered as 1, floor just above is numbered as 2 and so on till topmost floor is numbered as 8. They get different annual salaries. There are as many persons working above D as below the person who get 6lakh salary. 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 get 10lakh salary. There are as many floors between A and F as between F and B. D works above C and below H. C works just above the person who gets 3lakh salary and just below the person who gets 2lakh salary. 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.Solution
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: –
