• let total no of students 100, boy 60 and girl 40, so lunch taken by boy and girl respectively 60* 60/100=36 and 40* 40/100=16
  so total 52 students takes lunch out of 100 students..so required % is 52%

• Let total number of students be 100
  
  Boys : Girls = 6 : 4 (60 Boys and 40 Girls)
  
  60% boys => 60 X 0.6 = 36 boys
  40% girls => 40 X 0.4 = 16 girls
  
  36 + 16 = 52 = > 52 % takes Lunch
