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...
