(3600 × 40) / 120 = 1200(3600 × 10) / 120 = 300
(3600 × 30) / 120 = 900 (3600 × 15) / 120 = 450 (3600 × 25) / 120 = 750 |
| Total | 120 | 3600 |

125005000
7500 10000 5000 10000 |
(12500 × 3600) / 50000 = 900(5000 × 3600) / 50000 = 360
(7500 × 3600) / 50000 = 540 (10000 × 3600) / 50000 = 720 (5000 × 3600) / 50000 = 360 (10000 × 3600) / 50000 = 720 |
| Total | 50000 | 3600 |

(400 × 3600) / 1800 = 800(300 × 3600) / 1800 = 600
(500 × 3600) / 1800 = 1000 (250 × 3600) / 1800 = 500 (350 × 3600) / 1800 = 700 |

Question 5. The adjoining pie chart shows the expenditure of a country on various sports during year 2012. Study the pie chart carefully and answer the following questions:
(i) What percent of total expenditure is spent on cricket?
(ii) How much percent more is spent on hockey than that on tennis?
(iii) If the total amount spent on sports in 2012 is ₹1,80,00,000, then find amount spent on Badminton,
(iv) If the total amount spent on sports in 2012 is ₹2,40,00,000 then find the amount spent on cricket and hockey together.
Answer:
The given pie chart represents the expenditure of a country on various sports during the year 2012.
(i) Given that expenditure on a cricket = 900
(90 / 3600) × 100% = 25%
Therefore, 25% of expenditure is spent on cricket
(ii) Given that expenditure on a hockey = 750
(70 / 3600) × 100% = (125 / 6)%
= 20(5/6)%
Expenditure on tennis = 500
Hence, (50 / 3600) × 100% = (125 / 9)% = 13.9%
(125 / 6) – (125 / 9) = 125 / 18
= (375 – 250) / 18
= 125 / 18
= 6.95% more
Therefore, 6.95% more is spent on hockey than that on tennis
(iii) Total amount spent on sports = Rs 1,80,00,000
Total amount spent on Badminton = Rs 1,80,00,000 × (60 / 3600)
= Rs 30,00,000
(iv) If the total amount spent on sports = 2,40,00,000
Total amount spent on cricket and hockey together = 900 + 750
= 1650
= (1650 / 3600) × 2, 40, 00,000
= 1, 10, 00, 000
Question 6. The adjoining pie chart shows the number of students enrolled in class VI to class X of a school.
If 1440 students are enrolled from VI to X, then answer the following questions:
(i) How many students are enrolled in class VIII?
(ii) How many students are more in class IX than in class X?
(iii) What is the sum of students enrolled in VII and VIII?
(iv) Find the ratio of students enrolled in VI to students enrolled in X.
Answer:
The given pie chart represents the enrolment of students from class VI to class X in a school.
Total number of students enrolled from VI to X = 1440 students
(i) Enrolment of class VIII = (85 / 3600) × 1440 = 340 students
(ii) Difference in X and IX class enrolment = 750 – 500
= 250
(25 / 3600) × 1440 = 100 students
Therefore, 100 students are more in class IX than in class X
(iii) Sum of students enrolled in VII and VIII classes = 700 + 850
= 1550
(155 / 3600) × 1440 = 620 students
Therefore, the sum of students enrolled in Classes VI and VIII = 620 students
(iv) Ratio between the students enrolled in VI to students enrolled in X classes = 800: 500
= 8: 5
Therefore, the ratio between the students enrolled in VI to students enrolled in X classes is 8: 5
