If x represents the units digit of the number above, what is the value of x?
(1) The number above is divisible by 2 --> x is even. Not sufficient.
(2) The number above is divisible by 6 --> 8+9+2+1+3+2+2+4+x=31+x --> x could be 2 or 8 (in this case the number will be even, so divisible by 2 and the sum of its digits will be a multiple of 3, thus it will be divisible by 3). Not sufficient.
(1)+(2) x could be 2 or 8. Not sufficient.
Answer: E.
