The table shows the number of pupils who wear watches in three Primary 6 classes in a school.
- How many pupils in the three classes do not wear watches?
- The total number of pupils who wear watches is the same as the total number of pupils in Class 6A. How many pupils in Class 6B wear watches?
(a)
Total number of pupils not wearing watches
= 24 + 15 + 14
= 53
(b)
Total number of pupils in Class 6A
= 24 + 2
= 26
Number of pupils wearing watches in Class 6B
= 26 - (2 + 12)
= 26 - 14
= 12
Answer(s): (a) 53; (b) 12
