Sol: The total students is clubs can be found out using the relation of venn - diagram  
  
 
 
 
 
 
 
 
  
 As per question  
  only drama club = 60 i.e., a = 60  
  only dance club = 80 i.e.,  c = 80 
  only maths club = 30 i.e., g = 30 
  all time clubs = 2 i.e., e = 2 
 both Drama and Dance Clubs = 40 i.e.,  b + e = 40 ? b = 40 – 2 = 38 
 both Dance and Maths Clubs = 12 i.e., e + f = 12 ? f = 12 – 2 = 10 
 both Drama and Maths clubs = 7 i.e., d + e = 7 ? d = 7–2 = 5 
 Thus, three students to who are in at least one of the  clubs = a+b+c+d+e+f+g 
          = 60+38+80+5+2+10+30 = 225 
 This represents only 25% of students as remaining 75% are not in only of the clubs, So,  
  25% of total students = 225
