If the average (arithmetic mean) of 5 positive temperatures is p degrees Fahrenheit, then the sum of the 3 greatest of these temperatures, in degrees Fahrenheit, could be:  Select:
A) 6p B) 4p C) 5p/3 D) 3p/2 E) 3p/5
The sum of three greatest should be more than sum of two lowest.   The total sum is; 5p   A. 6p; 6p is more than 5p. Not possible.   B. 4p; 5p-4p=p(Possible)   C. 5p/3; 10p/3; 10p/3 &gt; 5p/3. Not possible   D. 3p/2; 7p/2; 7p/2 &gt; 3p/2. Not possible   E. 3p/5; 22p/5; 22p/5 &gt; 3p/5. Not possible.   Ans:4p
