The table shows the number of pupils who wear glasses in three Primary 2 classes in a school.
- How many pupils in the three classes wear glasses?
- The total number of pupils who wear glasses is the same as the total number of pupils in Class 2B. How many pupils in Class 2A do not wear glasses?
(a)
Total number of pupils wearing glasses
= 16 + 24 + 14
= 54
(b)
Total number of pupils in Class 2B
= 3 + 24
= 27
Number of pupils wearing glasses in Class 2A
= 27 - (3 + 12)
= 27 - 15
= 12
Answer(s): (a) 54; (b) 12
