Answer:

OK.....

Total marks =100...

Let be 8x,5xand 7x....

So when we add 8x+5x+7x =100... That is our equation...

20x=100

x=100/20...

x=5.....

So when we have to put the value of x... We get answer....

8(5)=40

5(5)=25

7(5)=35....

40 +25+35 =100 marks....

That is our proportianol question solved....

Hope it helps...
