On the basis of given bar graph in question ,
Sum of deficit from years 1987 to 1995 = 2200 + 3100 + 2100 + 2800 + 2600 + 3600 + 4200 + 2600 = 23200 millions
Total number of years = 8Average deficit = 23200 = 2900 million 8
∴ Required ratio = Number of years in which the trade deficit is above the average deficit : Number of years in which the trade deficit is below the average deficit
Correct Option: A

∴ Required ratio = Number of years in which the trade deficit is above the average deficit : Number of years in which the trade deficit is below the average deficit
∴ Required ratio = 3 : 5

According to given bar graph in question ,
The daily payment made to each worker which contains 9 workers = $ 35
Required total daily payment = 35 × 9 = $ 315Correct Option: B
According to given bar graph in question ,
The daily payment made to each worker which contains 9 workers = $ 35
Required total daily payment = 35 × 9 = $ 315
Hence , The total daily payment made to the group which contains 9 workers is $ 315 .
