Solution

The correct option is C 35
The total number of customers = 200

Sales of salty snacks at A = $\frac{10}{40}$ $\times$ 200

= 50
Sales of salty snacks at B = $\frac{13}{40}$ $\times$ 200

= 65

Sales of salty snacks at C = $\frac{17}{40}$ $\times$ 200

= 85

Arranging the data in order, we get

50, 65, 85

Range = Maximum value - Minimum value

Minimum value = 50

Maximum value = 85

Range = 85 - 50 = 35

Hence, the range of the data = 35
