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