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 $mathematical expression$ is $mathematical expression$ ? $mathematical expression$ $mathematical expression$	Yes	No	A (1 alone)
2	Is $mathematical expression$ an integer? $mathematical expression$ is an even number $mathematical expression$ is a multiple of $mathematical expression$	No	Yes	B (2 alone)
3	Is $mathematical expression$ an even number? $mathematical expression$ is even $mathematical expression$ is odd	Yes	Yes	D (Either)
4	What is the value of $mathematical expression$ ? $mathematical expression$ $mathematical expression$	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 $mathematical expression$ and $mathematical expression$ are and so discover the value of $mathematical expression$ . Therefore the answer is C.
5	Is $mathematical expression$ an odd number? $mathematical expression$ is an even number $mathematical expression$ is divisible by 3	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.
