**Page 196**

**Ex 9.2 Class 6 Maths Question 1. Total number of animals in five villages are as follows : Village A : 80 Village B : 120 Village C : 90 Village D : 40 Village E : 60**

Prepare a pictograph of these animals using one symbol ⊗ to represent 10 animals and answer the following questions :

(a) How many symbols represent animals of village E?

(b) Which village has the maximum number of animals?

(c) Which village has more animals : village A or village C?

**Answer**

We can draw the pictograph for the given data as shown below

Village | Number of Animals ⊗ – 10 animals |

Village A | ⊗⊗⊗⊗⊗⊗⊗⊗ |

Village B | ⊗⊗⊗⊗⊗⊗⊗⊗⊗⊗⊗⊗ |

Village C | ⊗⊗⊗⊗⊗⊗⊗⊗⊗ |

Village D | ⊗⊗⊗⊗ |

Village E | ⊗⊗⊗⊗⊗⊗ |

(a) There are 60 animals in village E. So 6 symbols represent animals of village E

(b) Village B has 120 animals which is the maximum number among these villages.

(c) Village A has 80 animals and village C has 90 animals. Clearly village C has more animals than village A

**Ex 9.2 Class 6 Maths Question 2. Total number of students of a school in different years is shown in the following table**

Years | Number of students |

1996 | 400 |

1998 | 535 |

2000 | 472 |

2002 | 600 |

2004 | 623 |

**A. Prepare a pictograph of students using one symbol to represent 100 students and ****answer the following questions:**

**(a) How many symbols represent total number of students in the year 2002?**

**(b) How many symbols represent total number of students for the year 1998?**

**B. Prepare another pictograph of students using any other symbol each representing 50 students. Which pictograph do you find more informative?**

**Answer**

– 100 students | |

1996 | |

1998 | |

2000 | |

2002 | |

2004 |

A

(a)Total number of students in the year 2002 represents 6 symbols

(b) Total number of students in the year 1998 represents 5 complete and 1 incomplete symbols.

B. Second is more informative

∞ – 50 students | |

1996 | ∞∞∞∞∞∞∞∞ |

1998 | ∞∞∞∞∞∞∞∞∞∞ο |

2000 | ∞∞∞∞∞∞∞∞ο |

2002 | ∞∞∞∞∞∞∞∞∞∞∞∞ |

2004 | ∞∞∞∞∞∞∞∞∞∞∞∞ο |
