Study the given graph and answer the question that follows.
The graph shows the sales of three products: P, Q and R by four companies: A, B, C and D.

What percentage is the total production by company C, of the total production by company A?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 100%.
Total sales by Company C = 9 + 8 + 6 = 23
Total sales by Company A = 9 + 8 + 6 = 23
Required percentage = (23/23) × 100 = 100%
Therefore, the total production by Company C is 100% of the total production by Company A.
