Average production of rice = Sum of the total production of rice in states total numbers of states Correct Option: B
As per given bar graph , we can see that
The production of rice in states
A = 8 million tonnes
B = 10 million tonnes
C = 4 million tonnes
D = 4 million tonnes
E = 2 million tonnesAverage production of rice = Sum of the total production of rice in states total numbers of states = 8 + 10 + 4 + 4 + 2 = 28 million tonnes 5 5
= 5.6 million tonnes
Direction: The bar graph given below shows annual result of different classes of a school. Study the graph carefully and attempt the question that follow:
 In which of the following classes pass percentage of girls is less than the average pass percentage of the school?

Average pass percentage of the school = Total number of pass Boys and girls / 14
Correct Option: A
Average pass percentage of the school = Total number of pass Boys and girls / 14
Average pass percentage of the school = (80 + 45 + 80 + 70 + 40 + 50 + 90 + 70 + 80 + 55 + 50 + 80 + 70 + 50/14 = 910)/14 = 65%
Therefore, it is clear that pass percentage of the girls in III and VI classes is less than the average pass percentage of the school.
 Average pass percentage of boy in classes II and III is equal to average pass percentage of girls in which of the following classes?

As per graph
Average pass percentage of the boys in classes II and III = 70 + 50/2 = 120/2 = 60%
Try option one by one and solve the question.Correct Option: C
As per graph
Average pass percentage of the boys in classes II and III = 70 + 50/2 = 120/2 = 60%
As per given graph we can find that
Average pass percentage of the boys in classes VI and Vii = 50 + 70/2 = 60%
Therefore. average pass percentage of boys in classes II and III is equal to the average pass percentage of girls in classes VI and VII.
 Result of which class shows maximum difference between pass percentage of the girls and the boy?

Calculate the difference between pass percentage of girls and boys in classes.
Correct Option: A
Difference between pass percentage of girls and boys in class I = 80  45 = 35%
Difference between pass percentage of girls and boys in class II = 80  70 = 10%
Difference between pass percentage of girls and boys in class III = 50  40 = 10%
Difference between pass percentage of girls and boys in class IV = 90  70 = 20%
Difference between pass percentage of girls and boys in class V = 80  55 = 25%
Difference between pass percentage of girls and boys in class VI = 80  50 = 30%
Difference between pass percentage of girls and boys in class VII = 70  50 = 20%
Hence, it is clear that result of class I shows maximum difference between pass percentage of the girls and the boys.
