Direction: Study the information given in each of these questions and then answer the questions.
 Based on given graph, Answer the below question.
Out of a total 550 students, how many students did not prefer Math or Economics?

View Hint View Answer Discuss in Forum
∵ Total numbers of students do not prefer Maths or Economics = % of Total numbers of students do not prefer Maths or Economics x Total numbers of students
Correct Option: D
From above given graph , we have
Total numbers of students = 550
Numbers of students prefer Maths = 12 %
Numbers of students prefer Economics = 16 %
Total numbers of students prefer Maths or Economics = 12 + 16 = 28
Total numbers of students do not prefer Maths or Economics = (100  28 )% = 72%
∴ Total numbers of students do not prefer Maths or Economics = % of Total numbers of students do not prefer Maths or Economics x Total numbers of students∴ Total numbers of students do not prefer Maths or Economics = 72 x 550 = 396 100
Direction: Study the following graph carefully to answer the questions that follow : Distance (in Km) traveled by 5 different trucks in a day.
 What is the ratio of the distance traveled by Truck A to the distance traveled by Truck D?

View Hint View Answer Discuss in Forum
Required ratio = The distance traveled by Truck A : The distance traveled by Truck D
Correct Option: C
As per given above graph , we have
The distance traveled by Truck A = 475
The distance traveled by Truck Truck D = 425
Required ratio = The distance traveled by Truck A : The distance traveled by Truck D
Required ratio = 475 : 425 = 19 : 17
 The distance travelled by Truck E is approximately what percent of the total distance travelled by Track B and C together?

View Hint View Answer Discuss in Forum
Required percentage = Total distance covered by E x 100 % Total distance covered by B and C together
Correct Option: D
As per given graph , we can see that
Total distance covered by E = 575 Km , Total distance covered by B and C together = 350 + 550 = 900 KmRequired percentage = Total distance covered by E x 100 % Total distance covered by B and C together = 575 x 100 ≈ 64% ≈ 62 % 900
 What is the average distance traveled by all the trucks together?

View Hint View Answer Discuss in Forum
Required Average distance covered by all the trucks = Total distance covered by all the trucks Total number of the trucks
Correct Option: D
Given in the bar graph :
Distance traveled by Trucks A = 475 , B = 350, C = 550, D = 425, E = 575,
Total distance covered by all the trucks = 475 + 350 + 550 + 425 + 575 = 2375 Km
Total number of the trucks = 5Required Average distance covered by all the trucks = Total distance covered by all the trucks Total number of the trucks Required Average distance covered by all the trucks = 2375 = 475 5
Direction: Study the following graph and answer the questions given below:
 If in April the crude oil price would have been lesser than the given by Rs. 223 per metric tonne then how much would have been the percentage increase in price over the earlier month?

View Hint View Answer Discuss in Forum
In April, crude oil price = Rs. 4800 per metric tonne.
So, reduced crude oil price = 4800  223 = Rs. 4577Correct Option: D
In April, crude oil price = Rs. 4800 per metric tonne.
So, reduced crude oil price = 4800  223 = Rs. 4577
Hence, required percentage = 4577  3980/3980 x 100 = 15%
