Ada and Paul received their scores on three tests. On the first test, Ada's score was 10 points higher than Paul's score. On the second test, Ada's score was 4 points higher than Paul's score. If Paul's average (arithmetic mean) score on the three tests was 4 points higher than Ada's average score on the three tests, then Paul's score on the third test was how many points higher than Ada's score?	Choices:
A) 9
B) 14
C) 17
D) 23
E) 26
My take is Option D (23)   I followed a simple approach (explained below):   Test 1: Ada's score = Paul's score + 10   Test 2: Ada's score = Paul's score + 4   Avg. of Paul's score = 4 points higher than Avg. of Ada's score   This implies that : Sum of Paul's score [3 Tests] = 12 points higher than Sum of Ada's score [3 Tests] (12 points higher since 3 points were given in terms of average of 3 scores)   So, Paul needs to score 23 points higher than Ada in Test 3, since Paul needs to compensate for the lower score in test 1 and Test 2 ( 26 = 10 + 4 + 12)   26
