There are many benefits to timing your practice, including:

Statement 1 --> Not sufficient because b can be 4938 or any multiple of 4938. Therefore, b has got multiple values and therefore this statement is insufficient.

Statement 2--> f = 6 so e can be 7 or 8 Therefore insufficient.

Statement 1 & 2 together are insufficient. So my answer is E. But the book says its B as they say c=3, d = 4, e =5. But my question is stem doesn't say they are consecutive integers so it can't be? Guys - am I reading something wrong over here? can you please help?

in these kinds of questions, actually how did you know that the question meant that c,d,e and f represent non zero different digits? it didn't say that the digits are different, so for example, you could have d and e =8, so I believe that the question should have mentioned that these are different non zero digits, and NOT ONLY saying that they are non zero digits.

(2) c>d>e>f and f = 6 c, d, e, and f cannot be equal. _________________
