DIRECTIONS for the question: The question below is followed by two statements marked I and II. Mark as your answer.
What was A’s score in fourth aptitude test?
Statement 1: A’s score in the fourth test was 12 points higher than the average score in the first three tests written
Statement 2: A’s score on the fourth test raise the average test score from 80 to 85
A)
If the data in statement (1) alone is sufficient to answer the question
B)
If the data in statement (2) alone is sufficient to answer the question
C)
If the data in both the statements together are needed to answer the question
D)
If either statement (1) alone or statement (2) alone is sufficient to answer the question
E)
If neither statement (1) nor statement (2) suffices to answer the question
B
Statement I: Here the average score of the first three tests are not known. So we cannot find the score of the fourth test.
Statement II: Since the average after the fourth test increased by 5, so the total must have been increased by 5 × 4 = 20. Hence the score in the fourth test is 80 + 20 = 100.
Therefore statement II is sufficient.
