Question

ram got 8 marks more than shyam in an examinations anil got 4marks more than ram in the same examinations if all three of them got 128 marks together as a total ram marks would be

Answer 1

let,
 anil's mark be x
 shyam's mark be y.

so, ram mark = 8 + y
      ram mark = 4 + x

so, 8+y = 4+x
      x-y = 4 

now, x+y+6+x = 128
        2x+y = 122

now solve the above

x - y = 4
2x + y = 122

then x = 43

therefore, ram's mark = 43 + 4 = 47 marks 

Answer 2

Let marks of shyam be x
Then marks of ram = x+8
Marks of anil = x+12

Total marks = 128
x+x+8+x+12= 128
3x +20 = 128
3x = 128-20
3x = 108
x = 108/3

x = 36 = Marks of shyam.

Marks of Ram = x+8
= 36+8
= 44

Marks of Anil = x+12
= 36+12
=48

If you satisfied mark it brainliest.
