Directions: Following is the data required the number of students who...
Number of students who like only coffee = 28/100 × 200 = 56
Number of students and who like coffee = 55/100 × 200 = 110
Number of students who like both coffee and tea but not cold drink = 30 - 18 = 12
Number of students who like both coffee and cold drink but not Tea = 110 - 56 - 30 = 24
Number of students who would like both tea and cold drink but not coffee =25/100 × 24 = 6
Number of student who like either only tea or only cold drink = 186 - (56 + 12 + 24 + 18 + 6) = 70
Number of students who like only tea = 4 / 7×70=40
Number of student who like only cold drink = 70 - 40 = 30
Complete the Venn diagram:
Number of student who like at most 1 item
= number of student who like no item + number of student who like exactly 1 item
= 14 + 56 + 40 + 30 = 140
Hence, the correct option is (D).
