-
- 50
- 55
- 65
- 80
Correct Option: B
According to given bar graph , we have
Number of families in daily income interval 800-900 = 40
Number of families in daily income interval 900-1000 = 15
Required number of families = Number of families in daily income interval 800-900 + Number of families in daily income interval 900-1000
Required number of families = 40 + 15 = 55
