The table shows the number of Primary 2 students in Xavier School who participated in a Mathematics class.
- How many Primary 2 students did not participate in the training?
- What is the enrolment of Primary 2 students in Xavier School?
(a)
Number of students who did not participate in each class:
Class 2A → 33 - 22 = 11
Class 2B → 31 - 23 = 8
Class 2C → 35 - 31 = 4
Class 2D → 37 - 33 = 4
Class 2E → 33 - 25 = 8
Total number of students who did not participate
= 11 + 8 + 4 + 4 + 8
= 35
(b)
Total enrolment
= 33 + 31 + 35 + 37 + 33
= 169
Answer(s): (a) 35; (b) 169
