Answer:
200 tulips 
Explanation:
The computation of the number of tulips are shown below:
Given that 
Ratio of number of tulips to number of ratios is 2:3 we can write 8:12
And, the peonies to roses are 1:4 we can write as 3:12
 So, 
Tulips : Roses : Peonies 
 8:12:3 
 Now 
Total units of flowers + 8 + 12 + 3 
 = 23 
 For tulips it would be 
= 575 × 8 ÷ 23 units 
 = 200 tulips
