Answer 1

The correct option is C 7

The given chart is


Let us find the average sales in shop 1 and 2.

The data set for shop1:

40, 55, 62, 45, 73

The mean of the data set is the sum of the data divided by the number of data values

Mean = $\frac{sumofalldata}{numberofdata}$

Mean = $\frac{40+55+62+45+73}{5}$

= 55

The data set for shop2:

55, 60, 65, 54, 76

Mean = $\frac{sumofalldata}{numberofdata}$

Mean = $\frac{55+60+65+54+76}{5}$

= $\frac{310}{5}$

= 62

Difference in the average sales of shop2 and shop1 = 62 - 55

= 7

Hence, the average sales of shop2 is 7 more than average sales of shop1.
