The pie chart given below represents the number of stationery items sold in a month at a shop. If the total no. of items sold was 1080, find the number of pens, notebooks, books and other items sold.
Pens - 225; Notebooks - 300; Books - 195, Others - 360
We know if x fraction of total items is shown on a pie chart, angle θ = x×360o
⇒ x = θ360∘ ; where x =Number of particular items soldTotal number of items sold
∴ Number of particular items sold = θ360∘×1080
other items =120∘360∘ ×1080 = 360
Notebooks =100∘360∘ ×1080 = 300
Books = 65∘360∘ ×1080 = 195
Pens = 75∘360∘ ×1080 = 225
