Answers to part II of the data sufficiency mini quiz.
Remind yourself what the answers A-E stand for with 1-2-TEN.
| # | Question | Is 1 sufficient? | Is 2 sufficient? | Answer (A-E) |
|---|---|---|---|---|
| 1 | What percentage of R is S?
|
Yes | No | A (1 alone) |
| 2 | Is `m/n` an integer?
|
No | Yes | B (2 alone) |
| 3 | Is `x` an even number?
|
Yes | Yes | D (Either) |
| 4 | What is the value of a + b?
|
No | No. | Since neither on it's own can answer the question the answer to the question could be C (Together) or E (Neither). In this case using both pieces of information you can work out what a and b are and so discover the value of a + b. Therefore the answer is C. |
| 5 | Is `y` an odd number?
|
No | No | Since neither on it's own can answer the question the answer to the question could be C (Together) or E (Neither). In this case even using both pieces of information together you can't work out whether y is odd. Therefore the answer is E. |
