A. 3, 8, 24 B. 7, 9, 17 C. 6, 9, 12 D. 5, 15, 18 E. 9, 10, 13 IMO ESince in the question stem it states as Only one of them Divisible by 3We can straight a way eliminate B, because all are ODD. A,C & D > more than a number is divisible by 3. Hence eliminate. E. Single digit number 9 and divisble by 3 we can take this. Hence E Correct. E  Correct.

I didnt get your point on eliminating E. The number of stamps only one purchased was divisible by 3.Could that not be Cecilia with 9 stamps. I choose this and marked E.

A. 3, 8, 24 B. 7, 9, 17 C. 6, 9, 12 D. 5, 15, 18 E. 9, 10, 13 We are given that the number of stamps Cecilia purchased was equal to a single digit, the number of stamps only one of them purchased was divisible by 3, and that number of stamps one of them bought was an even number. Looking at our answer choices, we need to find an answer choice that only has only one number that is a multiple of 3, so A, C, and D are not possible. We are left with B and E. We see that in answer choice B none of the numbers are even, so that leaves us with the only possible correct answer of E: 9, 10, and 13. Answer: E

Such a stupid question..the number of stamps only one of them purchased...should be only one of them purchased. The grammar on some questions is just terrible! Using faulty grammar to trick people
