Question

What is the difference between the average demand and the average production of the five companies taken together?

• A. 1400
• B. 400
• C. 280
• D. 138
• A. 1.8
• B. 1.5
• C. 2.5
• D. 1.11

Answer 1

The Correct Option is C

Step 1 — Recall the data from the bar chart:
• Company A → Demand = 3000, Production = 1500
• Company B → Demand = 600, Production = 1800
• Company C → Demand = 2500, Production = 1000
• Company D → Demand = 1200, Production = 2700
• Company E → Demand = 3300, Production = 2200

Step 2 — Calculate the total demand of all companies:
Total Demand = 3000 + 600 + 2500 + 1200 + 3300 = 10,600

Step 3 — Calculate the total production of all companies:
Total Production = 1500 + 1800 + 1000 + 2700 + 2200 = 9,200

Step 4 — Find the average values:
Average Demand = 10,600 ÷ 5 = 2,120
Average Production = 9,200 ÷ 5 = 1,840

Step 5 — Find the required difference:
Difference = Average Demand − Average Production
= 2,120 − 1,840 = 280

Final Answer:
The correct option is (C): 280.

Answer 2

Step 1 — Recall the production values from the chart:
• Company A → Production = 1500
• Company D → Production = 2700

Step 2 — Frame the ratio:
We need to find how many times the production of Company D is compared to Company A.
So, Required Ratio = Production of D ÷ Production of A.

Step 3 — Substitute the values:
= 2700 ÷ 1500
= 1.8

Step 4 — Interpretation:
This means Company D produces 1.8 times the number of TVs compared to Company A.

Final Answer:
The correct option is (A): 1.8.
