Question

in an examination 100 marks are distributed among three questions so that they are proportional to 8,5,7. find the marks for each​

Answer 1

Step-by-step explanation:

Total marks = 100

Dividation = 8:5:7

That is = 8x+5x+7x=100

= 20x=100

x=100/20

Therefore x = 5

8x = 8×5= 40

5x = 5×5= 25

7x = 7×5= 35

Therefore the marks for each question are :-

40, 25, 35..
