As per the given bar graph , we have
Required amount = Number of worker × mean monthly wages
Required amount = 3 × 1050 + 8 × 1150 + 5 × 1250 + 4 × 1350 + 9 × 1450 + 8 × 1550 + 6 × 1650 + 7 × 1750
Required amount = 3150 + 9200 + 6250 + 5400 + 13050 + 12400 + 9900 + 12250Correct Option: B

According to given bar graph , we have
Number of workers placed in the lowest wage group 1000 - 1100 = 3
Number of workers placed in the highest wage group 1700 - 1800 = 7
Required ratio = Number of workers placed in the lowest wage group 1000 - 1100 : Number of workers placed in the highest wage group 1700 - 1800Correct Option: A
According to given bar graph , we have
Number of workers placed in the lowest wage group 1000 - 1100 = 3
Number of workers placed in the highest wage group 1700 - 1800 = 7
Required ratio = Number of workers placed in the lowest wage group 1000 - 1100 : Number of workers placed in the highest wage group 1700 - 1800
Required ratio = 3 : 7
