A student needs an average of 88 across four tests. The first three scores are 84, 90, and 86. What score is needed on the fourth test?
Pick an answer
Correct!
Not quite. The correct answer is highlighted.
Correct answer to question 17 (Arithmetic Reasoning): 92
Method
Work backwards from the total the average requires. Four tests averaging 88 need 88 x 4 = 352 points, and the first three supply 260, so the fourth test must score 352 - 260 = 92.
