Here is a question that I cannot figure out
If the Average (mean ) of 5 positive temperatures is x degrees fahrenheit, then the sum of the 3 greatest of these temperatures, in degrees Fahrenheit, could be
Please provide solutions along with your answer choice. Thank you
Sum of all five numbers is 5x so sum of 3 greatest numbers must be greater than half of the full sum i.e. >2.5x
definitely A is impossible.
B could be a possibility as it is >2.5x
c is actually 1.67x so not possible.
D is actually 1.5x so not possible.
E is 0.6x definitely not possible
Thats why only option left is B and hence it is the answer.
