**Q V) a) Look at the
pictograph showing the strength of students in a primary school. Complete the
table and answer the questions that follow:**

S. No. | Class | No. of Students | Total |

1 | I | ¥ ¥ ¥ ¥ ¥ ¥ ¥ ¥ | 8 x 5 = 40 |

2 | II | ¥ ¥ ¥ ¥ ¥ ¥ ¥ | 7 x 5 = 35 |

3 | III | ¥ ¥ ¥ ¥ ¥ ¥ | 6 x 5 = 30 |

4 | IV | ¥ ¥ ¥ ¥ ¥ ¥ ¥ ¥ | 8 x 5 = 40 |

5 | V | ¥ ¥ ¥ ¥ ¥ | 5 x 5 = 25 |

KEY ( 1 ¥ = 5 students)

i) Which class has the maximum number of students?
**CLASS I** and
**CLASS IV**

ii) Which class has the minimum number of students?
**CLASS V **and
**CLASS III (here class V has minimum number i.e 25 while class III has
30) **

iii) Which two classes have the same number of students?
**CLASS I** and
**
CLASS IV.** They have
**40** students each.

iv) The total number of students of class I and II is
**
75 **than the total number of students of
class IV and V

v) The total number of students is
**170**

**b) An aeroplanes is flying with a speed opf 1250 km
per hour. How much time will it take to cover a distance of 5000 km?**

**Answer: Cross Mulitply**

**1 hour distance covered ==== 1250 km**

**? How much time will it take =====to cover 5000 km**

**? x 1250 = 5000 x 1 **

**? = 5000/1250 = 4 hours will take to cover a
distance of 5000 km.**

**c) Find out:**

**i) In the following figure find angle AOC**

**Answer: Angle AOC = 180 - angle BOC = 180 - 60 = 120
**

**ii) Arrange the following in the ascending order**

**62.230, 32.055, 32.505, 62.320, 5.12**

**Answer: Last number 5.12 convert to 5.120
(adding zero after decimal point does not change the value
of the number)**

**Now compare and the result is: 5.120, 32.055, 32.505,
62.230, 62.320**

**iii) Put > , < or = in the box**

**306.230
<
300 + 6 = 3/10 + 2/100**

**Now evaluate 300 + 6 + 3/10 + 2/100 = 306 + 0.3 + 0.02
= 306.32**

**iv) Turn the figure by making a quarter turn and draw
the next figure.**

**v) Write the following as decimal 16 9/100
**

**Answer:**

**The above number which is mixed fraction when solved
as improper fraction we get**

**16 x 100 + 9 / 100 = 1609/100 = 16.09 is the decimal
form of the above mixed fraction.**

**d) An aquarium is 150 cm long, 120 cm broad and 60 cm
high. What volume of water it can hold?**

**Answer: Volume of water in aquarium = length x breath
x height**

**= 150 x 120 x 60 = 10,80,000 cm 3**

**e) Compare Which one is greater?**

**i) Length of a table is 150 cm and breath is 60 cm**

**ii) Length of a box is 50 cm, breath is 60 cm and
height is 20 cm.**

**Answer: In first you are given area and second you are
given volume so you cannot compare the two.**

**But you can compare the length and breath of the two
and decide which one is greater.**

**i) 150 x 60 = 9000**

**ii) 50 x 60 = 3000**

**Therefore the first one is greater then the second
one.**
