We could also say that we've got 100 flowers, forcing our bouquets to be some factor of 100.

That leaves 5 and 10 as options, but 10 won't work because we can't divide 15 bulbs into 10 bouquets without cutting them into fractions.

Since all the tulips should be used and since the white to red ratio must be the same in all the bouquets, the white to red ratio in each bouquet must be 15:85 or 3:17. Thus, for some integer x, the number of white tulips in each bouquet is 3x and the number of red tulips in each bouquet is 17x. So, each bouquet contains 3x + 17x = 20x tulips. To maximize the number of bouquets, we should take x to be as small as possible. In this scenario, since the number of tulips cannot be zero or a negative number, the smallest possible integer value of x is 1. Then, each bouquet contains 20(1) = 20 tulips and there are at most 100 / 20 = 5 bouquets.

This is direct HCF question . Answer is HCF of 15 and 85 which is 5.

15 = 5*3
85 =5*17

so each bouquet will have 3 white tulips and 17 red tulips.

Answer is B
