  1.    56 inches
  2.    52 inches
  3.    68 inches
  4.    64 inches
 Discuss Question
Answer: Option B. -> 52 inches
:
B
Given:
1 drop = 4 inches of rain
Number of drops on Saturday =4drops
Number of drops on Sunday =9drops
Thereforeinches of rain on Saturday and Sunday
=(4+9)×4
=13×4=52inches
Question 2. The daily rainfall data recorded in a week is shown below. On which day of the week is the rainfall the highest? (1 drop = 1 inch rainfall)

  1.    Monday
  2.    Thursday
  3.    Sunday
  4.    Both Sunday and Monday
 Discuss Question
Answer: Option B. -> Thursday
:
B
Byobserving the graph, (1 drop = 1 inch)
Rainfall recorded on Monday = 10 inches
Rainfall recorded on Tuesday = 06 inches
Rainfall recorded on Wednesday = 08 inches
Rainfall recorded on Thursday = 11 inches
Rainfall recorded on Friday = 07 inches
Rainfall recorded on Saturday = 04 inches
Rainfall recorded on Sunday = 09 inches
From above , we can see that Thursday had the heaviest rainfall.
Question 3. Number of columns in the table given below is ______.

 Discuss Question
Answer: Option B. -> 2
:
B
Data written vertically are called columns. Here, there are two vertical datas present under the name Item and Quantity. Thus, there are two columns present in the given table.
Question 4. The daily rainfall data recorded in a week is shown below. What is the total rainfall recorded on Thursday? (1 drop = 4 inches of rain) 
The Daily Rainfall Data Recorded In A Week Is Shown Below. W...
  1.    46 inches
  2.    42 inches
  3.    44 inches
  4.    34 inches
 Discuss Question
Answer: Option C. -> 44 inches
:
C
Given:
1 drop = 4 inches of rain
Rainfall recorded on Thursday = 11 drops
Therefore, the number of inches of rain on Thursday = 4×11=44inches
Question 5. Representation of data as rectangular bars with different lengths is called:
  1.    Bar graph
  2.    Pictograph
  3.    Data
  4.    Scale
 Discuss Question
Answer: Option A. -> Bar graph
:
A
Abar graphis agraphthat presents data with rectangularbars with heights or lengths proportional to the values that they represent.
Question 6. Find the frequency of "K"in the given data set: 
K, J, F, J, A, J, N, S, A, J, A, W, P, J, A, H, A, P, O, W, J, K, Z.
  1.    1
  2.    2
  3.    3
  4.    4
 Discuss Question
Answer: Option B. -> 2
:
B
The number of times a particular value of dataoccurs is known as frequency.
Here, in the given data set:
K, J, F,J, A, J, N, S, A, J, A, W, P, J, A, H, A, P, O, W, J, K, Z.
we observe that K is occurring twice, therefore the frequency of K is 2.
Question 7. Find the frequency of symbol ‘+’:
 ×, ×, ÷, -, ×, +, +, ÷, ×, +, -, +, +, -, ÷, ×
  1.    3
  2.    4
  3.    5
  4.    6
 Discuss Question
Answer: Option C. -> 5
:
C
The number of times a particular value of data occurs is known as frequency.
Given:
×, ×, ÷, -, ×, +, +, ÷, ×, +, -, +, +, -, ÷, ×
We observethat the '+'symbol is occurring 5 times and therefore the frequency of + is 5.
Question 8. Data available in unorganized form is called :
  1.    Bar graph
  2.    Raw data
  3.    Information
  4.    Organised data
 Discuss Question
Answer: Option B. -> Raw data
:
B
Raw data is the data that has not been organised well enough for use.
Example:
Given below are the marks (out of 25) obtained by 10 students of class (V A) in mathematics in a test.
18, 16, 12, 10, 5, 5, 4, 19, 20, 10
Question 9. The temperature of a certain place, recorded for ten days (in C) is as follows:6,8,0,3,2,0,1,5,4,4
How many days had a temperature of less than 4C?
  1.    4
  2.    3
  3.    2
  4.    5
 Discuss Question
Answer: Option D. -> 5
:
D
Arranging the data in ascending order, we get, 0,0,1,2,3,4,4,5,6,8.
On observing, there are 5 days(0,0,1,2,3) that had atemperature of less than 4° C.
Question 10. The number of members in 20 families are given as follows:
 4,6,5,5,4,6,3,3,5,5,3,5,4,4,6,7,3,5,5,7

How many families have less than 5 members?
  1.    7
  2.    8
  3.    6
  4.    5
 Discuss Question
Answer: Option B. -> 8
:
B
4, 6, 5, 5, 4, 6, 3, 3, 5, 5, 3, 5, 4, 4, 6, 7, 3, 5, 5, 7
Here, we see the number of families with3 members is 4 and with 4 members is also 4.
So, the number of families with less than 5 members is 8.
