• 3 boys are considered as 1 group.
  
  so 5 groups are there.
  
  They can be arranged in 5! = 120 ways

• 720 ways.
  
  By kept 3boys together(1) and arranging 4 girls with them
  5! = 5*4*3*2*1 = 120ways. (i.e., 4+1 =5)
  
  Possible arrangements of 3 boys in following ways
  3! = 3*2*1 = 6ways
  
  Now, arrange all with the boys together
  120*6 = 720ways
