Jane has exactly 3 times as many Canadian as non-Canadian stamps in her collection. Which of the following CANNOT be the number of stamps in Jane's collection?
(A) 96
(B) 80
(C) 72
(D) 68
(E) 54
Let \(X\) be Non Canadian stamp so Canadian stamp = \(3X\)
Total stamp will be = \(X + 3X = 4X\)
Now look at the option, any number not divisible by 4 is the answer.
Hence 54 is not divisible by 4, so option E
