The correct option is A 50, 60
The data set from the given graph is
20, 50, 40, 70, 55, 50, 80
The mode of the data set is the value or values that occur most often.
Hence, mode = 50
Range = Maximum value - Minimum value
Arranging the data in ascending order, we get
20, 40, 50, 50, 55, 70, 80
Range = 80 - 20 = 60
Hence, mode and range of the dataset are 50 and 60, respectively.
