Question 1139272
<br>
Since the problem involves the average of three numbers that are close together, challenge yourself to solve the problem by logical reasoning with some simple arithmetic.  It's excellent brain exercise.<br>
(1) The first score was 1 over the average.
(2) Therefore the second and third scores must combine to be 1 under the average.
(3) If two scores together are 1 under the average and those two scores differ by 3, then the scores are 1 over the average and 2 under the average.<br>
ANSWER: 2nd test score 2 under the average = 74; 3rd test score 1 over the average = 77.
