Question

Archana got 42% marks in science, 72% marks in maths and 55% marks in English. The maximum marks in each of the subjects were 150,100 and 110 respectively. What is her aggregate percentage?

Answer 1

I think so it would be done like this:
Marks in science = 42 upon 150 multiply by 100
                            = 28 marks
Marks in maths = 72 upon 100 multiply by 100 
                         = 72 marks 
Marks in english = 55 upon 110 multiply by 100
                            = 50 marks
I am not confirmed but I tried if it is wrong then I am sorry I don't ,now if you want overall percentage or what if it is wrong then plz tell me what do you want to take out

Answer 2

Find her Science marks:

42% x 150 = 0.42 x 150 = 63 marks

Find her Math marks:

72% x 100 = 0.72 x 100 = 72 marks

Find her English marks:

55% x 110 = 0.55 x 110 = 60.5 marks

Find her total marks :

63 + 72 + 60.5 = 195.5

Find the highest possible score:

150 + 100 + 110 = 360

Find her aggregate percentage:

Percentage = 195.5/360 x 100 = 54.3%

Answer: Her aggregate percentage is 54.3%
