Interesting Q, keep posting these GMATT :-D
IMO it should be like this
short-stemmed-40
of these 20 white,15-pink, 5 red

Long-stemmed-80

From second part-15/p=5/r or r=3p, and p+r=80 then r=20, p=60
The required percentage is 15/80*100 or 18,75% :?
I must be wrong....it is not among the ans




u did a small mistake. r=3p and r+p=80, then r-60 and p-20.
you took the opposite.
thus req ans= 60/80=75%

short-stemmed=40
- 20 white
- 15 pink
- 5 red

long-stemmed=80
- p pink
- 80-p red

15/(p+15)=5/(85-p)
3(85-p)=p+15
255-15=4p
p=60

20/80
Answer B
