In a contest to guess how many gumballs are in a jar, the guesses are 45, 41, 55, 50, and 43. All these guesses are wrong. They are off by 3, 7, 5, 7, and 2 (but not in that order). How many gumballs are in the jar?
Answer:
48.........Since two guesses were off by 7, and no other guesses were repeated, these values must refer to numbers at the opposite sides of the spread. The two extreme are 41 and 55.
41 + 7 = 48
55 - 7 = 48
