IMO : E
12, when divided by 7 leaves a remainder 5 & when divided by 9 leaves a remainder 3
So 12/6 remainder 0

75 , when divided by 7 leaves a remainder 5 & when divided by 9 leaves a remainder 3
So 75/6 remainder 3

So the answer is E

Imo E
From the fist condition we can not determine any value of X as there are two variable X=7a+5
a can any value
From statement 2
We have X=9b+3
From this also we can deduce whether X is divisible by 6
If taken together the equation becomes
63Q+12
Here Q is any positive integer
We see that both the statements taken together are not sufficient.
