The table shows the number of Primary 5 pupils in Oliver School who participated in a Chinese class.
- How many Primary 5 pupils did not participate in the training?
- What is the enrolment of Primary 5 pupils in Oliver School?
(a)
Number of pupils who did not participate in each class:
Class 5A → 33 - 23 = 10
Class 5B → 32 - 20 = 12
Class 5C → 36 - 32 = 4
Class 5D → 38 - 34 = 4
Class 5E → 34 - 22 = 12
Total number of pupils who did not participate
= 10 + 12 + 4 + 4 + 12
= 42
(b)
Total enrolment
= 33 + 32 + 36 + 38 + 34
= 173
Answer(s): (a) 42; (b) 173
