Answer: Option D. -> Shruti
:
D
The length of bar shows the value of data being represented. As the bar corresponding to Shruti is the smallest (corresponding to 0 value), she scored the least.

Answer: Option B. -> False
:
B
This statement is false. The information which can be represented by a bar graph can be represented by a pictograph too. However, the preference may vary depending upon convenience and the context.

Question 4. The bar graph shows the favourite subjects of 20 students in class VI 'B'. How many more of them prefer Mathematics to Science?
FAVOURITE SUBJECTS OF 20 STUDENTS
Here the horizontal axis is x axis which represents subjects and vertical axis is y axis which represents number of students. x axis represents subjects and the scale y axis 1 cm = 1 student.

Answer: Option C. -> 4
:
C
5 of them prefermathematics and only one preferscience.
So,5 - 1 = 4
Therefore mathematics is preferred by 4 more students than science.

a)Total numbers of cars soldin2002-2003 =(6 + 12 + 5 + 16 + 7) × 1000 = 46000
b)Total saleof Maruti over three years = (5 + 8 +15) ×1000 = 28000
c)Total saleof GM over three years = (12 + 17 + 17) × 1000 = 46000
Hence, the difference between the salesof GM and Maruti = (46000 - 28000) =18000

Each option: 1 Mark
Above data, shows the numbers of cakes Lara, Linda, Sara and Carol have in two weeks.
Numbers of cakes Linda has = (5 + 5)×5 = 50
Numbers of cakes Lara has = (8 + 8) ×5 = 80
Numbers of cakes Sara has = (4 + 4) ×5 = 40
Numbers of cakes Carol has = (6 + 7) ×5= 65
a)Numbers of cakes Linda has is 50.
b) Numbers of cakes Carol has is 65
Difference in Carol and Linda = 65 - 50 = 15.
c) Total numbers of cakes =50 + 80 + 40 + 65 = 235.
d) Highest number of cake = 80
Lowest number of cake = 40
So, their difference is the = 80- 40 = 40.

Data is a collection of numbers gathered to give some information.
Answer: Option C. -> C
:
C
The data in table C is organised.
It is organised in ascending order.
We can easily answer the questions asked from the data in table C as compared to other data sets.
Also, when the number of students is more, it's almost impossible to analyse the data if it is not organised.
If we store it in alphabetical order, it is hard to determine who scored the least marks or who scored the highest marks.
So A is not always the best way to organise for easy analysis.
