The table shows the number of pupils who wear scarves in three Primary 6 classes in a school.
- How many pupils in the three classes wear scarves?
- The total number of pupils who wear scarves is the same as the total number of pupils in Class 6B. How many pupils in Class 6A do not wear scarves?
(a)
Total number of pupils wearing scarves
= 18 + 20 + 12
= 50
(b)
Total number of pupils in Class 6B
= 6 + 20
= 26
Number of pupils wearing scarves in Class 6A
= 26 - (6 + 10)
= 26 - 16
= 10
Answer(s): (a) 50; (b) 10
