# In a Mathematics test, the following marks were obtained by 40 students. Arrange these marks in a table using tally marks.

**(a)** Find how many students obtained marks equal to or more than $ 7 . $

**(b)** How many students obtained marks below 4?"

To do:

We have to find

(a) The number of students who obtained marks equal to or more than \( 7 . \)

(b) The number of students who obtained marks below 4.

Solution:

Marks | Tally Marks | Number of students |

1 | || | 2 |

2 | ||| | 3 |

3 | ||| | 3 |

4 |
| 7 |

5 | 6 | |

6 | 7 | |

7 | 5 | |

8 | |||| | 4 |

9 | ||| | 3 |

(a) The number of students who obtained marks equal to or more than $7=$ The number of students who obtained 7 marks $+$ The number of students who obtained 8 marks $+$ The number of students who obtained 9 marks

$=5+4+3$

$=12$

(b) The number of students who obtained marks below $4=$ The number of students who obtained 3 marks $+$ The number of students who obtained 2 marks $+$ The number of students who obtained 1 mark

$=2+3+3$

$=8$
