Direction: The histogram, given below, shows the number of families of a locality having various daily incomes, as obtained by a survey. Observe the graph and answer the questions based on it.
-
The number of families, whose daily incomes are $ 800 or above, is
-
- 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
