Question

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.

• A. Pens - 220; Notebooks - 320; Books - 195; Others - 235
• B. Pens - 360; Notebooks - 320; Books - 175; Others - 225
• C. Pens - 390; Notebooks - 300; Books - 175; Others - 215
• D. Pens - 225; Notebooks - 300; Books - 195, Others - 360

Answer 1

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×360^o

⇒​ x = $\frac{\theta }{{360}^{\circ }}$ ; where x =$\frac{Numberofparticularitemssold}{Totalnumberofitemssold}$

∴​ Number of particular items sold = $\frac{\theta }{{360}^{\circ }}$​×1080

other items =$\frac{{120}^{\circ }}{{360}^{\circ }}$ ×1080 = 360

Notebooks =$\frac{{100}^{\circ }}{{360}^{\circ }}$ ×1080 = 300​

Books = $\frac{{65}^{\circ }}{{360}^{\circ }}$ ×1080 = 195

Pens = $\frac{{75}^{\circ }}{{360}^{\circ }}$ ×1080 = 225
