The table shows the number of students who wear hats in three Primary 4 classes in a school.
- How many students in the three classes do not wear hats?
- The total number of students who wear hats is the same as the total number of students in Class 4A. How many students in Class 4B wear hats?
(a)
Total number of students not wearing hats
= 28 + 19 + 12
= 59
(b)
Total number of students in Class 4A
= 28 + 4
= 32
Number of students wearing hats in Class 4B
= 32 - (4 + 10)
= 32 - 14
= 18
Answer(s): (a) 59; (b) 18
