The table shows the number of students who wear caps in three Primary 5 classes in a school.
- How many students in the three classes do not wear caps?
- The total number of students who wear caps is the same as the total number of students in Class 5A. How many students in Class 5B wear caps?
(a)
Total number of students not wearing caps
= 21 + 18 + 14
= 53
(b)
Total number of students in Class 5A
= 21 + 7
= 28
Number of students wearing caps in Class 5B
= 28 - (7 + 12)
= 28 - 19
= 9
Answer(s): (a) 53; (b) 9
