The table shows the number of pupils who wear hats in three Primary 2 classes in a school.
- How many pupils in the three classes do not wear hats?
- The total number of pupils who wear hats is the same as the total number of pupils in Class 2A. How many pupils in Class 2B wear hats?
(a)
Total number of pupils not wearing hats
= 22 + 19 + 13
= 54
(b)
Total number of pupils in Class 2A
= 22 + 7
= 29
Number of pupils wearing hats in Class 2B
= 29 - (7 + 11)
= 29 - 18
= 11
Answer(s): (a) 54; (b) 11
