Country Club has an indoor swimming club. Thirty percent of the members of a swim club have passed the lifesaving test. Among the members who have not passed the test, 12 have taken the preparatory course and 30 have not taken the course. How many members are there in the swim club?

• Totally 60 members are there in the swim club.
  
  30% passed the test.
  It means, 70% have not passed the test.
  
  Let the total number of members = X
  Then, 0.7X have not passed.
  
  Therefore,
  0.7X = 30 + 12
  0.7X = 42
  X = 42/0.7
  X = 60
  There are 60 members in the club.
• 12 years agoHelpfull: Yes(19) No(0)
• Not passed the test:30+12=42
  This No. is equivalent to 70%
  Thus, Total Number of of members in the club:
  42/70*100=60
• 12 years agoHelpfull: Yes(5) No(2)
• Remaining =70%
  70% of total=30+12
  total=(42*100)/70
  total=60

• There are 60 members in the swim club.
  30+12=42
  42/70*100=60

• 30% of members have passed the test.
  suppose 100 members are there.. 70 have not passed the test.
  12 taken prepatory course +30 not taken course=42 people have not passed the test.
  Equation would be
  70 ==> 42 people than,
  100==>?

  .
  Ans= 600people.

• 30%-passed
  70%-30+12
  70%-42
  70/100*x=42
  x=60
• 6 years agoHelpfull: Yes(0) No(0)
• 30%+30 = 70%+12
  40% = 18
  100% == ?
  ANs = 45
