• both will be required to give the answer....
  cz...
  
  10 bulls are black...therefore 40 cows are left..
  
  total 20 cattle are black in colour....
  
  therefore ...20-(no of bull which are always black)=10

• both together are not sufficient

• as
  from 1st stmnt
  no of cows=40
  now total cows nd bulls (cattle) is 50
  from 2nd stmnt
  40%of 50=20
  black animal in cattle=20
  20/50*40=16(cow black) i think
  ans both stmnt required..

• it can't be determined since we don't know about the color of bulls..they can either be black or white.
• 10 years agoHelpfull: Yes(1) No(0)
• Both statement required
  as Bulls are consider black animal and cows may be black or white
  
  Bulls + Black cow=40% of cattle
  10 + Black cow=40*50/100
  10+ Black cow=20
  Black cow=10

• cannot be determined, Because here not given how meny cows or bulls are black.
• 10 years agoHelpfull: Yes(1) No(0)
• both statements r insufficient to ans the question.here 40% means 20 cattles r black nd we have given 10 r bulls.now we dont know how mny bulls r black so we r unable to find the no of black cows.
