Is the positive integer Q divisible by 11?
Statement 1
(1) Q is a multiple of 777
If Q = 777 * 11 , Is the positive integer Q divisible by 11? - Yes
If Q = 777 * 1 , Is the positive integer Q divisible by 11? - No
This statement is not sufficient and we can eliminate A and D.
Statement 2
(2) Q is a multiple of 7
If Q = 7 * 11 , Is the positive integer Q divisible by 11? - Yes
If Q = 7 * 1 , Is the positive integer Q divisible by 11? - No
This statement is not sufficient and we can eliminate B
Combined
Q is a multiple of 7 and 777
If Q = 777 * 11 , Is the positive integer Q divisible by 11? - Yes
If Q = 777 * 1 , Is the positive integer Q divisible by 11? - No
This statement combined doesn't help either.
Option E
