Data Interpretation MCQ Questions and Answers - Bar Chart

Production of company D = 2700
Production of company A = 1500
$$\eqalign{ & h = \frac{\text{Production of company D}}{\text{Production of company A}} \cr & h = \frac{2700}{1500} \cr & h = \frac{9}{5} \cr & h = 1.8 \cr} $$

Number of companies having more demand than production = 3
Number of companies having more production than demand = 2
∴ Required ratio
= 3 : 2

Difference between demand and production of company A
= 3000 - 1500
= 1500
Difference between production and demand of company D
= 2700 - 1200
= 1500

Total production of the five companies
= 1500 + 1800 +1000 + 2700 + 2200
= 9200
Total demand of the five companies
= 3000 + 600 + 2500 + 1200 + 3300
= 10600
∴ Required difference
$$\eqalign{ & = \frac{1}{5}\left(10600-9200\right) \cr & = \frac{1}{5}\times1400 \cr & = 280 \cr} $$

Given $$x$$% of demand for company C = Demand for company B
$$\eqalign{ & \Rightarrow \frac{2500\times x}{100} = 600 \cr & \Rightarrow 25x = 600 \cr & \Rightarrow x = \frac{600}{25} \cr & \Rightarrow x = 24 \cr} $$
