The average of temperatures at noontime from Monday to Friday is 60; the lowest one is 45, what is the possible maximum range of the temperatures?
Choose one
A) 20	B) 25	C) 40	D) 45	E) 75

Rationale: "there are 5 days so the sum of temperature can be 60 * 5 = 300 lowest is 45 . to find the maximum range we can say the temperature was the lowest for 4 of the 5 days so 4 * 45 = 180 . on the fifth day it is 300 - 180 = 120 range is therefore 120 - 45 = 75 answer e"
Answer: E
