Direction: Study the graph and answer the following questions.
-
The average production of the companies A, B, C and that of the companies D, E are in the ratio :
-
- 85 : 147
- 86 : 147
- 86 : 149
- 87 : 149
Correct Option: B
From the given bar diagram , we see
Total production of the companies A, B and C = 1500 + 1800 + 1000
Number of companies A, B and C = 3
Total production of the companies D and E = 2700 + 2200
Number of companies D and E = 2
Required ratio = Average production of the companies A, B and C : Average production of the companies D and E
Required ratio 
Required ratio = 2 × 4300 : 4900 × 3 = 86 : 147
