In a class of 250 students, on JAN 2 15% of the girls and 10% of the boys are absent. If on 100% attendance there are 10 boys. Find the percentage present?

• Ans is 85.2%
  The reason is explained below:
  on 100% attendance,toital no of boys=10
  that means there are 240 girls and 10 boys in a class
  if 10% boys are absent, then it means that 1 boy is absent
  if 15% of girls are absent, then it means that (15/100)*240=36 girls are absent
  therefore no of students present=250-(1+36)=250-37=213
  % of no of students present=(213/250)*100=85.2%
