Introduction to Graphs MCQs

Ans. 4. Salary of Employees

Explanation: The business spends the most on the salary of the employee and the least on travel allowance and rent.

Ans. 1. Traveling Allowance and Rent

Explanation: The travel allowance and the rent has the same amount of expenditure, i.e, 1,00,000.

Ans. 2. 2,00,000

Explanation: Expenditure in traveling allowance = Rs.1,00,000

Expenditure in rent = Rs.1,00,000

So, the sum of the both heads = 1,00,000 + 1,00,000 = Rs. 2,00,000

The sum of expenditure on traveling allowance and rent is Rs. 2,00,000

Ans. 1. Rs. 1,050

Explanation:Saving is shown as 35° in the pie chart. 

                     The whole pie is of 360°

So, Saving = \({35 \over 360} \times 10,800\) = Rs.1,050

The savings of the family is Rs.1,050.

Ans. 1. Rs. 1,200

Explanation:  Expenditure on clothes shown on pie chart = 70°

Expenditure on education shown on pie chart = 30°

So, the difference of both = 70 - 30 = 40°

Difference amount = \({40 \over 360} \times 10,800\) = 1,200

The difference between the expenditure on clothes and food is Rs. 1,200.

Ans. 3. Rs. 5,400

Explanation: Expenditure on education shown in the pie chart = 30°

Expenditure on food shown in the pie chart = 150°

So, the sum will be = 150° + 30° = 180°

Sum amount = \({180 \over 360} \times 10,800\) = 5,400

The sum of expenditure on education and food is Rs. 5,400.

Ans. 1. 100

Explanation:  The number of students of class interval (0-5) = 100

The number of students of class interval (5-10) = 200

So, the difference = 200 - 100 = 100

The difference between the number of students of class interval (0-5) and (5-10) is 100 students.

Ans. 1. 800

Explanation: The number of students of class interval (20-25) = 500

The number of students of class interval (10-15) = 300

So, the sum = 500 + 300 = 800

The sum of students in the class intervals 20-25 and 10-25 is 800 students.

Ans. 1. 1^oF

Explanation: The temperature at 11hrs = 103^oF

The temperature at 13hrs = 104^oF

So the difference = 104^oF - 103^oF= 1^oF

The difference in temperature from 11hrs to 13hrs is 1^oF.

Ans. 4. 6^oF

Explanation: The temperature at 13hrs = 104^oF

The temperature at 21hrs = 98^oF

Fall in temperature = 104^oF- 98^oF= 6^oF

The fall in temperature from 13hrs to 21hrs is  6^oF

Ans. 1. The origin refers to the point 0, so the coordinates will be (0,0).

Explanation: The coordinates of the origin are (0,0) can be seen in the graph. It clearly shows that the point of origin is 0 for the x and y-axis.

Answer. 2. The coordinate point will be (3,5).

Explanation: The coordinates are always written in the format (x,y) So as the x-coordinate is 3 and the y-coordinate is 4, the coordinate point will be (3,5).

Ans. 2. The coordinates (4,5) and (5,4) are not the same.

Explanation: The coordinates are always written in the format (x,y). So for the coordinate (4,5), 4 is the x-coordinate and 5 is the y-coordinate, and for the coordinate (5,4), 5 is the x-coordinate and 4 is the y-coordinate. This can be clearly seen in the graph that the two coordinates have different positions.

Ans. Histogram

Ans. 1. Line graph

Ans. 2. Linear Graph

Ans. 2. 300

Explanation: The distance covered at 8 am = 50km

The distance covered at 9 am = 150km

The distance covered at 10 am = 200km

So,  Average distance = (50+150+200)3 = 4003= 300km

The average distance covered is 300km.

Answer: 3. Straight line without passing through the origin

Explanation: It can be clearly seen in the graph that the 3 coordinates will create a straight line without origin.

Ans. 1. The point (4,0) will lie on the x-axis.

Explanation: Since the y-coordinate is 0 so we can’t move in the upward direction. So the point (4,0) will lie in point 4 of the x-coordinate.

Ans. The point (0,0) lies in the origin.

Explanation: The origin is defined as the point (0,0). It is the point at which the x- and y-axes meet.
