The average of temperatures at noontime from Monday to Friday is 60; the lowest one is 40, what is the possible maximum range of the temperatures?
Choices.
A) 100	B) 25	C) 40	D) 45	E) 75

Rationale: "average = 60 , sum of temperatures = 60 * 5 = 300 as the min temperature is 40 , max would be 300 - 4 * 40 = 140 - - > the range = 140 ( max ) - 40 ( min ) = 100 answer : a"
Answer: A
