The table shows the number of Primary 1 students in Rael School who participated in a Chinese class.
- How many Primary 1 students did not participate in the training?
- What is the enrolment of Primary 1 students in Rael School?
(a)
Number of students who did not participate in each class:
Class 1A → 31 - 28 = 3
Class 1B → 30 - 20 = 10
Class 1C → 34 - 30 = 4
Class 1D → 36 - 32 = 4
Class 1E → 32 - 22 = 10
Total number of students who did not participate
= 3 + 10 + 4 + 4 + 10
= 31
(b)
Total enrolment
= 31 + 30 + 34 + 36 + 32
= 163
