Study the following table carefully and answer the questions given below it

 Percentages of Marks obtained by Six students in Six different subjects Subject Psychology (150) Sociology (120) Economics (80) Philosophy (75) Statistics (125) Geology (60) Student A 72 65 85 65 88 72 B 68 58 74 70 78 54 C 63 73 69 57 68 65 D 56 65 77 61 75 67 E 78 55 82 76 59 74 F 84 70 64 78 82 80 Note : Figures written in bracket under each subject indicate the maximum marks allotted for that subject

1. What is the difference between the total marks obtained by A in Psychology and Statistics together and the total marks obtained by F in these two subjects together ?
Solution :
Marks obtained by A :
In Psychology = 150 x (72/100) = 108

In Statistics = 88 x (125/100) = 110

So, total = 108 + 110 = 218

Marks obtained by F

In Psychology = (84x150) / 100 = 126

In Statistics = (82 x 125) / 100 = 102.50

So, Total = 126 + 102.50 = 228.50

So, Required difference = 228.50 - 218  = 10.5

2. What is the average percentage of Marks obtained by six students in Sociology ?
Solution :

Required average =  (65 + 58 + 73 + 65 + 55 + 70) / 6
= 386/6  = 193/3

3.  What are the average marks obtained by the six students in Philosophy out of 75 ?
Solution :

Marks obtained by :
A = (65 x 75) / 100 = 48.75

B = (70 x 75) / 100 = 52.50

C = (57 x 75) / 100 = 42.75

D = (61 x 75) / 100 = 45.75

E = (76 x 75) / 100 = 57

F = (78 x 75) / 100 = 58.50

So, Required average = (48.75 + 52.50 + 42.75 + 45.75 + 57 + 58.50) / 6

= 305.25 / 6   = 50.875

4. What are the total marks obtained by 'A' in Psychology. Economics and Geology together ?
Solution :
Marks obtained by A :
in Psychology = (72 x 150) / 100 = 108

in Economics = (85 x 80) / 100 = 68

in Geology = (72 x 60) / 100 = 43.2

So, Total = 108 + 68 + 43.2  = 219.2

5. Approximately what is the overall percentage of marks obtained by 'C' in all the subjects together ?
Solution :

We can determine the average of percentage
So, overall percentage = (63 + 73 + 69 + 57 + 68 + 65) / 6

= 395 / 6 = 65.8  = 66%
