A storekeeper checked his stock of five commodities: F 215, G 113, H 108, K 216, M 68. What angle will commodity H represent on a pie chart?

Worked solution (try it first)
  1. Total stock: 215+113+108+216+68=720215 + 113 + 108 + 216 + 68 = 720.
  2. Each item gets 360∘720=0.5∘\frac{360^\circ}{720} = 0.5^\circ.
  3. Commodity H has 108 items: 108×0.5∘=54∘108 \times 0.5^\circ = 54^\circ, option D.
