The table shows the number of students who wear watches in three Primary 5 classes in a school.
- How many students in the three classes do not wear watches?
- The total number of students who wear watches is the same as the total number of students in Class 5A. How many students in Class 5B wear watches?
(a)
Total number of students not wearing watches
= 30 + 19 + 10
= 59
(b)
Total number of students in Class 5A
= 30 + 6
= 36
Number of students wearing watches in Class 5B
= 36 - (6 + 8)
= 36 - 14
= 22
Answer(s): (a) 59; (b) 22
