Solution

The correct option is D

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 =120360 ×1080 = 360

Notebooks =100360 ×1080 = 300​

Books = 65360 ×1080 = 195

Pens = 75360 ×1080 = 225
