The table shows the number of students who wear spectacles in three Primary 1 classes in a school.
- How many students in the three classes do not wear spectacles?
- The total number of students who wear spectacles is the same as the total number of students in Class 1C. How many students in Class 1A wear spectacles?
(a)
Total number of students not wearing spectacles
= 20 + 10 + 26
= 56
(b)
Total number of students in Class 1C
= 26 + 5
= 31
Number of students wearing spectacles in Class 1A
= 31 - (8 + 5)
= 31 - 13
= 18
Answer(s): (a) 56; (b) 18
