None of these

Discuss Question

Answer: Option C. -> The only product that does not show an increasing
Statement C is not true, since both A and B have not shown an increasing trend.

Question 147. Directions (1 - 5): The following chart represents Demand and Production for 5 companies ABCDE. On the basis of the graph answer the questions.

If x% of demand for company C equals demand for company B, then x equals.

Discuss Question

Answer: Option A. -> 24
Given $$x$$% of demand for company C = Demand for company B
$$\eqalign{
& \Rightarrow \frac{2500\times x}{100} = 600 \cr
& \Rightarrow 25x = 600 \cr
& \Rightarrow x = \frac{600}{25} \cr
& \Rightarrow x = 24 \cr} $$

Question 148. Directions (1 - 5): The following chart represents Demand and Production for 5 companies ABCDE. On the basis of the graph answer the questions.

The difference between average demand and average production of the five companies taken together is-

Discuss Question

Answer: Option B. -> 280
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
$$\eqalign{
& = \frac{1}{5}\left(10600-9200\right) \cr
& = \frac{1}{5}\times1400 \cr
& = 280 \cr} $$

If the production of company D is h times of the production of company A. Then h equals:

Discuss Question

Answer: Option D. -> 1.8
Production of company D = 2700
Production of company A = 1500
$$\eqalign{
& h = \frac{\text{Production of company D}}{\text{Production of company A}} \cr
& h = \frac{2700}{1500} \cr
& h = \frac{9}{5} \cr
& h = 1.8 \cr} $$

Discuss Question

Answer: Option D. -> B
Difference between demand and production of company A
= 3000 - 1500
= 1500
Difference between production and demand of company D
= 2700 - 1200
= 1500
