Answer: i) 30 students for chemistry
ii) 21 students for only one subject
iii) 61 students
Step-by-step explanation: from the question we got 30 students registered for chemistry. number students only for biology = (27-18) = 9
number of students only for chemistry = (30-18) = 12
number of student registered for only one subject = (12+9)= 21
number of students registered for neither two subjects = {100-(9+12+18)} = 61
5 and 2/7 would be closer to the whole number 5 than 6
Your answer would be 5
