According to the table shown, how many vehicles are parked in the basement of the apartment?
Answer: Option C. -> 90 vehicles
:
C
In the table shown, each vehicle image represents 5 vehicles.
Number of vehicles in Row 1 =4×5 = 20vehicles.
Number of vehicles in Row 2 = 5×2 = 10 vehicles.
Number of vehicles in Row 3 = 4 × 5 = 20 vehicles.
Number of vehicles in Row 4 =5 ×5 = 25 vehicles.
Number of vehicles in Row 5=5×3 = 15 vehicles.
On adding all the vehicles in all the rows, we get
= 20 + 10 +20 + 25 + 15 = 90 Vehicles.
∴ 90 Vehicles are parked in the basement of theapartment.

A pictograph is a way of showing data using images. It is generally represented by showing images on vertical lines.
Question 23. Look at the graph shown, thickness of bars and gap between bars are identical, it shows details of vehicles purchased by members of the residences of same apartment during the year.
1 unit of length represents 2 vehicles purchased.
Number of Vehicles Purchased during the Year
Who has purchased the maximum number of vehicles during the year?
Here the horizontal axis is x axis which represents number of vehicles and vertical axis is y axis which represents name of people. The scale for y axis is 1 cm = 1 name and x axis 2 cm = 1 vehicle .
1 unit of length represents 2 vehicles purchased.

Answer: Option A. -> Sophia
:
A
By looking into the graph you can answer that Sophia has maximum number of cars during that year. Length of bar with respect to Sophia's shows largest, thus she has more number of vehicles than other members in the apartment.

Answer: Option D. -> 69
:
D
From the graph we can see that Jessica's score for English is 60.
Jenny's score in English is 15% more than Jessica's.
⇒60+15%×60=60+15100×60
=60+9=69
∴ Jenny's score in English =69

Concept: 1 Mark
Solution: 1 Mark
We can see from the above tally that every 5th mark is crossed.
∴ The count of straight lines = 5 + 2 = 7
The number of straight linesis 7.
Question 28. In a class of five students, the table shows the marks obtained by 5 students in Maths, Physics and Chemistry. Find the answer of the following questions. [4 MARKS]

:
Each option: 1 Mark
Marks scored by roll no. 1= 67 +78 + 67 = 212
Marks scored by roll no. 2 = 57 +78 +75 = 210
Marks scored by roll no.3 = 78 + 64 + 72 = 214
Marks scored by roll no. 4 = 84 + 60 + 69 = 213
Marks scored by roll no.5 = 69 + 70 + 73 = 212
a)Maximum marks is scored by roll no. 3 = 214
b)Yes, marks scored by both rollnumbers 1 and roll no. 5 are the same = 212
c)Least marks is scored by roll no. 2 = 210
d) Aggregate marks scored by roll no. 4 is 213

d) Find the total number of workers who worked on Saturday in shift 3.
[4 MARKS]
:
Each part: 1 Mark
Total numbers of workers in the industry is 1000
So, workers of shift 1+ workers of shift 2 + Workers of shift 3 =1000
Workers of shift 3 in Monday = 1000 - (300 + 520) = 180
Workers of shift 2 in Tuesday = 1000 - (270 + 470) = 260
Workers of shift 3 in Wednesday = 1000 - (350 + 450) = 200
Workers of shift 2 in Thursday = 1000 - (400 + 250) = 350
Workers of shift 1 in Friday = 1000 - (420 + 330) = 250
Workers of shift 3 in Saturday= 1000 - (500 + 250) = 250
a)The numbers of workers worked on Tuesday in shift 2 = 260
b)Numbers of workers in shift 2 =(520 + 260 + 450 + 350 + 420 + 250 ) = 2250
c)Total numbers of workers in shift 3 =( 180 + 470 + 200 + 250 + 330 + 250 ) = 1680
d) Total number of workers who worked on Saturday in shift 3 = 1000 - (500 + 250) = 250
