Study the given graph carefully and answer the question that follows.
In which of the following years was the sales of company 1 exactly half of the total sales of companies 2 and 3 together in that year?
Answer & explanation
Correct answer: option 3
Lets solve one by one for each option.
1. 2019
Total sale of company 2 & 3 = 80 + 85 = 165
Sale of company 1 = 70
Percentage of sale of company 1 to company 2 & 3 together = \(\frac{70 }{165}\) × 100
= 42.42% ≠ 50%
2. 2021
Total sale of company 2 & 3 = 70 + 85 = 155
Sale of company 1 = 75
Percentage of sale of company 1 to company 2 & 3 together = \(\frac{75}{155}\) × 100
= 48.38% ≠ 50%
3. 2016
Total sale of company 2 & 3 = 40 + 60 = 100
Sale of company 1 = 50
Percentage of sale of company 1 to company 2 & 3 together = \(\frac{50 }{100}\) × 100
= 50%
4. 2020
Total sale of company 2 & 3 = 80 + 75 = 155
Sale of company 1 = 60
Percentage of sale of company 1 to company 2 & 3 together = \(\frac{60 }{155}\) × 100
= 38.70% ≠ 50%
Ans :- 2016
