In a team of 12 persons 1/3 are women and remaining are men.To obtain a team with 20% women how many men should be hired.
1.8
2.4
3.2
4.none

• ans is 8
  women=4, men=8
  let x men should be hired
  4/12+x=20/100
  after solving we get x=8

• 8 ans.
  in 12 person w:m = 1/3 : 2/3 = 1:2 (here 2 part=8)
  in x person w:m = 1/5 : 4/5 = 1:4 (so 4 part=16)
  additional man=16-8=8

• 20% women means 80% man should be hired
  8+x/12+x =80/100
  solve this,then x=8

• total women=1/3*12 = 4 => rest 8 is men.
  
  Let A be total team strength.
  
  so A * 20% = 4 (since women number is constant)
  
  therefore A = 4/(20%)= 20
  men to be hired = 20-8 = 12

• since the no of women remains constant....
  let "m" extra men are hired....
  then...
  (20/100)*(12+m)=(1/3)*12
  solving... m=8

• Now women is 4.After the adding women will be 1/5. So total person will be 20. So extra men are 8.

• women needs to be 20% so men wil be 80%. now let men to be added be x. prevsly men wer 8.(new numb of men (i.e x+8)/total men(i.e x+8)+women(4)) * 100 = 80%. dis is possibl nly when x=8.

• number of womens in team of 12 members is 4..
  we need to make 4 members as 20% of newly formed team by adding mens...
  so here 4---->20%

• current ratio m:w=1:2 w=4
  desired ratio=m:w=4:1
  but w=4 is constant
  so, multiply 4:1 with 4 to keep number of women=4
  so, 4:1= 16:4
  in new formation, when w=4, m=16
  so, total men required 16-8=8
