the second statement gives us all multiples of 9 till 100 excluding 9... insuff

combined we still have two values 27 or 72.. insuff

(1) 10a+b=14 not suff
(2) clearly not suff
1+2) 2 digit multiples of 9: 18,27,36,45,54,63,72,81,90,99 -> could be 27: 2x7=14 or 72: 7x2=14
Answer E

Question : x = ab = ? where a and b are digits of number x

Statement 1 : The product of the two digits is 14. 
i.e. a*b = 2*7
but number may be with 27 or 72. Hence, 
NOT SUFFICIENT

Statement 2 : x is divisible by 9. 
Number may be 18, 27, 26 etc. Hence, 
NOT SUFFICIENT

Combining the two statements  
Number may still be 27 or 72. Hence, 
NOT SUFFICIENT

Answer: option E

Question Type: Yes/No  What is the value of two-digit integer x?

Given information from the question stem: x is a two-digit integer. For this question you can start with Statement 2 since that statement is more obviously not sufficient.

Statement 2 : x is divisible by 9. In other words, x is a multiple of 9. However, there are many two-digit multiples of 9, such as 18, 27, 36, etc. This is clearly not sufficient. Eliminate choices B and D.

Statement 1 : The product of the two digits is 14. What two-digit integers have a product of 14? 27 has a product of 14, as does 72. Because there is more than one value of x this statement is also not sufficient. Eliminate choice A.

Together : Taken together the two values used in Statement 1 still work here. Both 27 and 72 are multiples of 9, and both multiply to 14. Taken together the statements are not sufficient.

The correct answer is E.
