After end of the game 42liters of water is drank by the all. The find the no of boys and girls in the volley ball team.

• 7*3+9*1+4*3=42
  
  So 3 boy 1 coach and 3 girls

• 42-9=33lit of waters remaining
  7*3+4*3=21+12=33lit
  so, 3 boys ,3 girls are there in volley ball court
• 11 years agoHelpfull: Yes(7) No(0)
• coach(1)-9 litrz
  remaining 42-9=33
  4*3=12
  7*3=21
  21+12=33
  so 3B ,3G,1C
  (NOTE-COACH WILL BE 1 ONLY)
• 11 years agoHelpfull: Yes(4) No(0)
• girls=2,
  boys=1,
  coach=3,
  2*4 + 1*7 + 3*9 = 42
  
• 11 years agoHelpfull: Yes(2) No(9)
• Vikrant how you know that boys=3 and girls=3
• 11 years agoHelpfull: Yes(2) No(1)
• 4G+7B+9C = 42 (since, coach wil be only one as we know , c=1)
  4G+7B=42-9
  =>4G+7B=33
  the above eqn is satisfied if G=3 and B=3.
  Therefore no. of boys = 3 and no. of girls = 3
• 11 years agoHelpfull: Yes(2) No(0)
• every team has 1 coach so, 42-9=33
  then assume
  case1 4B=28 then (33-28=5)so it is not.
  case2 3B=(7*3)=21 3G=(4*3)=12
  21+12+9=42
  so ans is 3boys, 3girls & 1coach.
