Hi Bunuel, The question is incorrect. IMO, it should be "30 of the gray cats are NOT domestic ones"

A. 90. B. 80. C. 50. D. 40. E. 25. Hi Bunuel, There seems to be some typo error... 200  70 street cats and 130 are therefore domestic... again 200  110 are gray, so 90 are nongray... 110 gray cats  30 are domestic, so remaining 11030 = 80 gray cats should be street cats... BUT the total street cats are ONLY 70

Answer is C. SC=70,DC=130 GC=110,NGC=90
So SC,GC30 and DC,GC=80 NGC,SC=40 and NGC,DC=50
SC=stray cats DC=domesticated cats GC=Gray cats NGC=Non Gray Cats

110 gray cats including 80 domestic cats. 130 domestic cats in total.
So 130  80 = 50 nongray domestic cats.

A. 90. B. 80. C. 50. D. 40. E. 25. Since 70 are street cats, 130 are domestic. Since 110 are gray, 90 are not gray. Of the 110 gray cats, there are 30 gray cats that are street cats, so there are 110  30 = 80 gray cats that are domestic. Thus, there are 130  80 = 50 cats that are domestic and not gray. Answer: C
