Direction: Study the bar diagram and answer the following questions.
-
The ratio of average demand to average production of companies B and D is
-
- 1 : 5
- 2 : 5
- 3 : 5
- 4 : 5
Correct Option: B
According to given bar graph , we have
Average production of companies B and D = ( 2700 + 1800 ) ÷ 2 = 4500 ÷ 2 = 2250
Average demand of companies B and D = ( 1200 + 600 ) ÷ 2 = 1800 ÷ 2 = 900
Required ratio = 900 : 2250 = 2 : 5
