The table shows the number of Primary 3 students in Zane School who participated in a Science class.
- How many Primary 3 students did not participate in the training?
- What is the enrolment of Primary 3 students in Zane School?
(a)
Number of students who did not participate in each class:
Class 3A → 30 - 20 = 10
Class 3B → 30 - 25 = 5
Class 3C → 34 - 30 = 4
Class 3D → 36 - 32 = 4
Class 3E → 32 - 27 = 5
Total number of students who did not participate
= 10 + 5 + 4 + 4 + 5
= 28
(b)
Total enrolment
= 30 + 30 + 34 + 36 + 32
= 162
Answer(s): (a) 28; (b) 162
