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?

2016

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
