Q) How many engineering graduates participated in a yoga workshop that was conducted only for Arts, Commerce and Engineering graduates?

I) The number of Arts graduates are twice the number of Commerce graduates and thrice that of Engineering graduates.
II) There were 30 Arts graduates who participated in the workshop.

• 10 Engineering graduates
  
  Given,Art graduates=30
  So Commerce graduates=30/2=15 and
  Engineering graduates=30/3=10
  
• 10 years agoHelpfull: Yes(37) No(1)
• Both statements I nd II together are necessary to answer the question
  
  A = 2C+3E
  A = 30
  2C+3E = 30
  Substitute values for C nd E to get 30
  C=1, C=2 ll not produce 30
  C=3, E=8
  2(3) + 3(8) = 30
  
  Hence both are necessary
  
  Ans : Both statements I nd II together are needed
• 10 years agoHelpfull: Yes(14) No(9)
• Sorry it might be "Both are not sufficient" bcozzz
  2C+3E =30
  There are many possible values of (C,E) ll yield 30... (3,8), (6,6)(9,4)(12,2)
  Possible values of E ll be 8,6,4,2...
  So we cant find the exact no. of engg graduates...
  
  Hence "Both I nd II are not sufficient to answer the question"
• 10 years agoHelpfull: Yes(3) No(15)
• Both Are taken into sufficent and answer is 10
• 10 years agoHelpfull: Yes(3) No(0)
• both statements are nessasary to ans the question
• 9 years agoHelpfull: Yes(2) No(0)
• 55
  Explanation: The number of art graduates are 30 so the number of engineering graduates are 10 and number of commerce graduates are 15
• 10 years agoHelpfull: Yes(1) No(1)
• 10 members
• 6 years agoHelpfull: Yes(1) No(0)
• a= 2c and a= 3e since a=30 then e= 30/3= 10
• 10 years agoHelpfull: Yes(0) No(0)
• Both are necessary to answer the question.
  
• 9 years agoHelpfull: Yes(0) No(0)
