#### Question 1:

The sale of electric bulbs on different days of a week is shown below:

Days |
Number of bulbs |

Monday | |

Tuesday | |

Wednesday | |

Thursday | |

Friday | |

Saturday | |

Sunday |

= 2 bulbs

Observe the pictograph and answer the following questions:

(i) How many bulbs were sold on Friday?

(ii) On which day maximum number of bulbs were sold?

(iii) If one bulb was sold at the rate of Rs 10, what was the total earning on Sunday?

(iv) Can you find out the total earning of the week?

(v) If one big cartoon can hold 9 bulbs. How many cartons were needed in the given week, more than 7, more than 8 or more than 9?

#### Answer:

(i) Number of figures of bulbs shown against Friday = 7

Given: 1 figure = 2 bulbs

∴ Total number of bulbs sold on Friday = 2 × 7 = 14

(ii) Sunday shows the maximum number of figure of bulbs, i.e., 9.

∴ On Sunday, maximum bulbs were sold.

(iii) Numbers of figures of bulbs shown against Sunday = 9

∴ Total number of bulbs sold on Sunday = 2 × 9 = 18

Given, the cost of each bulb = Rs. 10

∴ Total earning on Sunday = Rs. 10 × 18 = Rs. 180

(iv) Total number of figures of bulbs shown throughout the week

= 6 + 8 + 4 + 5 + 7 + 4 + 9 = 43

∴ Total number of bulbs = 43 × 2 = 86

∴ Total earnings of the week = Rs. 10 × 86 = Rs. 860

(v) Total number of bulbs = 86

Given that one big carton can hold 9 bulbs.

Therefore, for holding 86 bulbs, we need

$\frac{86}{9}=9\frac{5}{9}$ cartoons

So, more than 9 cartons are needed.

#### Question 2:

A survey was carried out in a certain school to find about different modes of transport used by students to travel to school each day. 30 student of class VI were interviewed and the data obtained was displayed in the form of a pictographs given below:

Look at the above pictograph and answer the following questions:

(i) How many students are using cycle or walking as a mode of travel?

(ii) Which is most popular mode of travel?

#### Answer:

(i) Number of students shown travelling to school using cycle = 3

Number of students shown walking to school = 8

∴ Number of students using cycle or walking as a mode of travelling to school = 3 + 8 = 11

(ii) The pictograph shows that the maximum number of students, i.e.,10, are using the school bus as a mode of travelling to school.

∴ The most popular mode of travelling to school is the school bus.

#### Question 3:

The number of girls students in each class of co.ed. Middle school is depicted by the following pictograph:

Class |
Number of girls |

I | |

II | |

III | |

IV | |

V | |

VI | |

= 4 girls

Observe the above pictograph and answer the following question:

(i) Which class has the maximum number of girl student?

(ii) Is the number of girls in class VI is less than the number of girls in class V?

(iii) How many girls are there in VII class?

#### Answer:

Based on the above pictograph, we can prepare the following chart to determine the number of girl students in each class.

Given, 1 figure = 4 girls

or

Class |
Numbers of girls |

I | 6 × 4 = 24 |

II | $4\frac{1}{2}\times 4=18$ |

III | 5 × 4 = 20 |

IV | $3\frac{1}{2}\times 4=14$ |

V | $2\frac{1}{2}\times 4=10$ |

VI | 4 × 4 = 16 |

VII | 3 × 4 = 12 |

VIII | $1\frac{1}{2}\times 4=6$ |

(i) From the chart we can easily say that the maximum number of girls, i.e., 24, are present in Class I

∴ Class I has the maximum number of girls.

(ii) Number of girls in Class VI = 16

Number of girls in Class V = 10

∴ Number of girls in Class VI is not less than the number of girls in Class V.

Ans: No

(iii) From the chart we can say that there are 12 girls in Class VII.

Martin | $9\frac{1}{2}\times 100=950$ |

Ranjit singh | 8 × 100 = 800 |

Joseph | $4\frac{1}{2}\times 100=450$ |

(i) On the above chart we can see that Martin sold the maximum number of baskets, i.e., 950 fruit baskets.

Ans: Martin

(ii) Anwar sold 700 fruit baskets.

(iii) On the above chart we can see that Anwar sold 700 fruit baskets, Martin sold 950 fruit baskets and Ranjit Singh sold 800 fruit baskets. Therefore, Anwar, Martin and Ranjit Singh are the merchants who are planning to buy a godown for the next season.

Hindi | $5\frac{1}{2}\times 100=550$ |

English | 8 × 100 = 800 |

History | 2 × 100 = 200 |

Science | 4 × 100 = 400 |

Maths | $2\frac{1}{2}\times 100=250$ |

(i) From the above chart we can say that there are 800 English books in the library.

(ii) The calculation on the above chart shows that there are 250 Maths books in the library.

(iii) From the above chart we can say that the English books are maximum in number, as there are 800 books of that subject.

∴ English

(iv) From the above chart we can see that the History books are minimum in number, as there are only 200 books of that subject.

∴ History
