The table shows the number of Primary 5 students in Cody School who participated in a Mathematics class.
- How many Primary 5 students did not participate in the training?
- What is the enrolment of Primary 5 students in Cody School?
(a)
Number of students who did not participate in each class:
Class 5A → 32 - 20 = 12
Class 5B → 26 - 21 = 5
Class 5C → 30 - 26 = 4
Class 5D → 32 - 28 = 4
Class 5E → 28 - 23 = 5
Total number of students who did not participate
= 12 + 5 + 4 + 4 + 5
= 30
(b)
Total enrolment
= 32 + 26 + 30 + 32 + 28
= 148
Answer(s): (a) 30; (b) 148
