A two-digit even number is such that reversing its digits creates an odd number greater than
the original number. Which one of the following cannot be the first digit of the original
number?
(A) 1 (B) 3 (C) 5 (D) 7 (E) 9
The second digit must be larger than the first so that reversing
the digits will create a number greater than the original number.
There is no digit larger than 9, so (E) is the correct choice.
