In a class of 70 students, the ratio of boys and girls is 4 : 3. Ratio of boys playing cricket

and girls playing cricket is 2 : 1 and the ratio of boys not playing cricket and girls playing

cricket is 2 : 3, then find the number of girls playing cricket.

• Girls playing cricket=15
  
  Total number of boys=70*4/(4+3)= 40, so girls=30
  Let girls playing cricket=x, then boys playing cricket=2x
  So boys not playing cricket=(40 - 2x)
  Given ratio of boys not playing cricket and girls playing cricket=2:3
  => (40-2x)/x = 2/3
  => 120 -6x = 2x or x=15

• Total students =70
  boys=4x and girls=3x
  no. of boys in class = 70/7 *4=40 and similarly no. of girls= 70/7*3=30
  now we have ratio of boys and girls playing cricket = 2:1 therefore no. of girls playing cricket would be 30/3*1=10.
  Hence no. of girls playing cricket = 10
  so out of

  Ans: no. of girls playing cricket = 10
