Answer 1

We have,

Total number of pairs of shoes sold

= 130 + 120 + 90 + 40 + 20

= 400

Central angle of pie chart for each brands.

A = `130/400 xx 360^circ = 117^circ`

B = `120/400 xx 360^circ = 108^circ`

C = `90/400 xx 360^circ = 81^circ`

D = `40/400 xx 360^circ = 36^circ`

E = `20/400 xx 360^circ = 18^circ`
