Directions (11-15): Given below is the table showing the average marks scored by students of five various classes of five different schools in annual examination. Study the table carefully and answer the questions based on it. Q11. Students of class IV in school D scored a total of 7000 marks while the students of class VI of same school scored a total of 10,400 marks. Find the difference in number of students of these two classes.
25
15
40
12
18
Solution:
Number of students in class IV = 7000/280 = 25
Number of students in class VI = 10400/260 = 40
∴ Required difference = 15
Number of students in class VI = 10400/260 = 40
∴ Required difference = 15
Q12. In school E, the students of class V scored a total of 11900 marks. But in revision of mark sheet it was found that marks of five students were misread as 280, 370, 480, 450 and 320 instead of 420, 400, 310, 200 and 210 respectively. Find the new average (approximate) after correction:

Solution:
Q13. Which class has its average marks 160% of the average marks of class V of school B ? Class II school D
Class V school E
Class VI school C
Class II school B
class II school A
Solution:
Average marks of class V of school B = 200
So, 160% of average marks of class V of school B = 320 which is same as the average marks of class II of school A.
So, 160% of average marks of class V of school B = 320 which is same as the average marks of class II of school A.
Q14. Find the average of numerical value of average marks of class III, V, II and VI of schools C, E, D and A respectively.
336.5
327.5
