a)

White	Red	Blue
	5 units	2 units	x 3
7 units		3 units	x 2
14 units	15 units	6 units

14 : 15 : 6

b)

	White	Red	Blue	Total
Before	14 units	15 units	6 units	35 units
After	14 units	15 units – 50	6 units	35 units – 50

We know that after 5o red tulips were taken away, the red tulips made up 20% (1/5) of the total number of tulips. This means that if we multiply the quantity of red tulips by 5, it should equal the total number of tulips.

(15 units – 50) x 5 = 35 units – 50
75 units – 250 = 35 units – 50
75 units – 35 units = 250 – 50
40 units = 200
1 unit = 5

White tulips → 14 x 5
= 70

Blue tulips → 6 x 5
= 30

70 – 30 = 40 more white tulips than blue tulips
