The data on the mode of transport used by 720 students is given below. Complete the following table and answer the questions that follow. S.No. Mode of transport Number of students Central angle (i) Bus 120 720 × 360 ∘ = (ii) Cycle 180 720 × 360 ∘ = (iii) Train 240 × 360 ∘ = 120 ∘ (vi) Car 80 80 × 360 ∘ = (v) Scooter 100 720 × 360 ∘ = What percentage of students use cycle as mode of transport?

S.No. Mode of transport Number of students Central angle (i) Bus 120 720 × 360 ∘ = (ii) Cycle 180 720 × 360 ∘ = (iii) Train 240 × 360 ∘ = 120 ∘ (vi) Car 80 80 × 360 ∘ = (v) Scooter 100 720 × 360 ∘ = Given that, Total number of students = 720 Mode of transport = Cycle Number of students use cycle = 180 . We know that, Central angle is given by N u m b e r o f s t u d e n t s u s e p a r t i c u l a r m o d e o f t r a n s p o r t T o t a l n u m b e r o f s t u d e n t s u s e s t r a n s p o r t × 360 ° Central angle = 180 720 × 360 ° = 90 ° . Percentage of students uses cycle as transport = C e n t r a l a n g l e C o m p l e t e a n g l e × 100 = 90 360 × 100 = 1 4 × 100 = 25 % Hence, percentage of students uses cycles as mode of transport is 25 % .

In the month of July 2016 , a householder spend a part of his monthly salary, amounting to ₹ 7200 , on different items as given below Items Clothing Food Transport Education Other Amount Spent (in ₹) 600 4000 1200 400 1000 Draw a pie-chart showing the above information.

In a pie chart we can present data as sectors, the central angle of each sector is a part of a complete angle whose measure is 360 o . We need to find the central angle for each sector as follows: Central angle for the sector of Clothing = 600 7200 × 360 o = 30 o Central angle for the sector of Food = 4000 7200 × 360 o = 200 o Central angle for the sector of Transport = 1200 7200 × 360 o = 60 o Central angle for the sector of Education = 400 7200 × 360 o = 20 o Central angle for the sector of Other = 1000 7200 × 360 o = 50 o The piechart is as drawn below:
