Average pass percentage of boy in classes II and III is equal to average pass percentage of girls in which of the following classes?

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.

In class IV pass percentage of girls is the highest. Thereore in this class only number of failed girls is the minimum.

Average pass percentage of girls = Total number of girls for pass the class/7
Average pass percentage of girls = 80 + 80 + 40 + 90 + 80 + 50 + 70/7 = 490/7 = 70%
Therefore. in class VI pass percentage of boys is more than the average pass percentage of girls.

Average of the total taxation during the years = total taxation for all the years / 6.
Average of the total taxation during the years = 600 + 725 + 1260 + 1730 + 2400 + 625 = 7390/6 = 1231.7 crores

Increase in taxation in between the financial years 2005-06 and 2006-07
= Rs. (2400 - 1730) = RS. 670 crores

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.

As per given graph we can check that which state have the Highest graph for Rice and Lowest graph for Wheat.
From above given graph ,
The production of rice in state A = 16 billion tonnes
The production of wheat in state A = 8 billion tonnes
The production of rice in state B = 10 billion tonnes
The production of wheat in state B = 2 billion tonnes
? Required Difference = The production of rice - The production of wheat
State A ? (16 ? 8) = 8 billion tonnes
State B ? (10 ? 2) = 8 billion tonnes
Hence Answer will be states A and B both .

From above given bar graph , we can see that
The graph for rice and wheat is lowest for state D.
Hence the total production of rice and wheat in all the mentioned states is minimum in the state D.
Hence Required answer will be state D.

As per given bar graph , we can see that
Total production of rice in all state = (8 + 10 + 4 + 4 + 2) = 28 Lakhs tonnes
Total production of wheat in all state = (16 + 2 + 4 + 2 + 6) = 30 Lakhs tonnes
? Required ratio = Total production of Rice : Total production of Wheat
? Required ratio = 28 : 30 = 14 : 15
