Study the table given below, and answer the question that follows.

If there are 55 chairs, how many chairs need to be drawn to complete the picture table?

• A. 2
• B. 4
• C. 10
• D. 6

Answer 1

The correct option is A 2

Say: Let's observe the picture table and identify the number of chairs in each class to find the number of chairs in class 4.

Steps:
- We know that = 5 chairs.
- So, the number of chairs in each class:
Class 1 = 15
Class 2 = 10
Class 3 = 20
- Three classes have 15 + 10 + 20 = 45 chairs in all.
- As there are 55 chairs in total, to find the number of chairs in Class 4, we will subtract the number of chairs in three classes from the total number of chairs.
- So, 55 – 45 = 10
- Therefore, class 4 will have 10 chairs.
- So, we need to draw 2 chairs for class 4.
- Hence, option D is the answer.

WB: If required, use the whiteboard to find the number of chairs in each class and then find the number of chairs in Class 4 as shown.
