The table shows the number of pupils who wear watches in three Primary 5 classes in a school.
- How many pupils in the three classes wear watches?
- The total number of pupils who wear watches is the same as the total number of pupils in Class 5B. How many pupils in Class 5C wear watches?
(a)
Total number of pupils not wearing watches
= 10 + 27 + 19
= 56
(b)
Total number of pupils in Class 5B
= 8 + 27
= 35
Number of pupils wearing watches in Class 5C
= 35 - (8 + 8)
= 35 - 16
= 19
Answer(s): (a) 56; (b) 19
