E. 74

Questions involving ratios can often be solved without explicit calculation, based on logical properties.

We'll look for such an approach, a Logical methodology.

Saying that there is a ratio of 8:3 between the flowers is the same as saying that there are a total of 11x flowers, 8x of the first kind and 3x of the second.

So the difference between them is 8x-3x=5x and our answer must be divisible by 5.

Only (B) fits.

(B) is our answer.
