About Pie Charts

A pie chart (or a circle graph) is a circular chart divided into sectors, illustrating proportion. In a pie chart, there are length of each sector (and consequently its central angle and area), is proportional to the quantity it represents. When angles are measured with 1 turn as unit then a number of percent is identified with the same number of centiturns. Together, the sectors create a full disk. It is named for its resemblance to a pie which has been sliced. The earliest known pie chart is generally credited to William Playfair's Statistical Breviary of 1801. Pie charts are common in business and journalism.

Related Formula

In pie charts, from geometry, we know that the area the sector of a circle must be proportional to the corresponding value of the component.

Since the sum of all the central angle is 360°, we have Central angle of the component
= {(value of the component/Total value) x 360} °.

Total of Pie Charts = 360°

If you need to make any angle into percentage then =

Answer of Data Interpretation

1. Answer : (D)
Required number = (17% of 27300) + (14% of 24700)
= 4641 + 3458 = 8099.

2. Answer : (D)
Required ratio = (21% of 24700)/(14% of 27300) = 19/14

3. Answer : (B)
Students of institute M at graduate level = 17% of 27300 = 4641.
Students of institute S at graduate level = 14% of 27300 = 3822.
Total number of students at graduate in institutes M and S = (4641 + 3822) = 8463.

4. Answer : (D)
Required ratio = (21% of 24700)/(13% of 27300)
= (21 x 24700)/(13 x 27300)
= 19/13

5. Answer : (C)
Required number = (15% of 24700) + (12% of 24700)
= 3705 + 2964
= 6669.

6. Answer : (B)
(40+10) = 50% (from first chart)

7. Answer : (B)
40:15 = 8:3

8. Answer : (D)
Tourist traffic from India to other countries is 20%.
Amongst this 20%, 25% of traffic from India to Switzerland.
So, 25% of 20% = (25/100 x 20/100)
= 5% corresponds to the Indian traffic in Switzerland.
5 % corresponds to Switzerland is 25 lakh.
Over all Indian traffic to all the countries = (25 x 100/5) = 500 lakh (total traffic)
Hence 15% of total traffic = 15/100 x 500 = 75 lakh.

9. Answer : (A)
A pie chart is of 360°.
Hence Skin = 1/10 of 360° = 36°
So Percentage of Skin in pie chart = (36°/360° x 100)% = 10%
Total percentage = (10 / 24) x 100 = 41.6666667 %

10. Answer : (D)
A pie chart is of 360°.
Hence 1/5 of 360° = 72°
So Percentage of Bones in pie chart = (72°/360° x 100)% = 20%
So Percentage of skin in pie chart = 1/10 of 360° = 36°
= (36°/360° x 100)% = 10%
20% + 10% = 30% is made up of either bones or skin. Hence, 70% is made up of neither.

11. Answer : (D)
It cannot be determined since the respective distributions are not known.

12. Answer : (D)
Although it seems to be Commodore, the answer cannot be determined due to the fact that we are unaware of the break-up of the sales value and volume of companies compromising the other categories.

13. Answer : (A)
If we assume the total sales to be 100 in the first year, IBM's sales would go up by 50% (from 28 to 42) contributing an increase of 14 to the total sales value.
Similarly, Apple's increase of 15% would contribute an increase of 2.1 to the total sales value. The net change would be 14 + 2.1 on 100. (i.e., 16.1%)

14. Answer : (D)
IBM accounts for 28% of the share by value and 10% of the share by volume.
28% of 1650000 = 28 x 1650000/100 = 462000
10% of 1500 = 10 x 1500/100 = 150
Therefore, average unit sale price = 462000/150 = 3080.

15. Answer : (B)
20% of the total funds to be arranged = Rs. (20% of 57600) crores
= Rs. 11520 crores is near about Rs. 11486 crores.
Rs. 11486 crores is the amount of funds to be arranged through External Assistance.

16. Answer : (C)
Shortage of funds arranged through External Assistance = Rs. (11486 - 9695) crores = Rs. 1791 crores.
Increase required in Market Borrowing = Rs. 1791 crores.
Percentage increase required = ( 1791 / 29952 x 100) % = 5.98% or 6%. App.

17. Answer : (C)
Amount permitted = (Funds required from Toll for projects of Phase II) + (10% of these funds)
= Rs. 4910 crores + Rs. (10% of 4910) crores
= Rs. (4910 + 491) crores

= Rs. 5401 crores.

18. Answer : (C)
Central angle corresponding to Market Borrowing
= (29952 + 11486 + 5252 + 4910 + 6000) = 57600
= ( 29952/57600 x 360°) = 187.2º

19. Answer : (B)
Required ratio = 4910 / 29952
=1 / 6.1 or 1:6 app

20. Answer : (A)
Percentage of money spend on Tennis = ( 45 / 360 x 100) % = 12 ½ %

21. Answer : (D)
