Answer 1

Answer:

44

Step-by-step explanation:

let Mark of shyam= x

then Mark of ram= 8+ x

and marks of anil= 4+mark of ram=4+8+x=12+x

now according to question,

mrk of shyam+mark of ram+mark of anil=128

(x)+(8+x)+(12+x)=128

3x+20=128

3x= 128-20

3x=108

x=36

now Rams mark=8+x=8+36=44

Answer 2

Answer:

(2) 44

Step-by-step explanation:

let Rams mark=X

then Shyams mark=X-8 and

Anils mark =X+4

So we can say that;

X+(X-8)+(X+4)=128

ie, 3X-8+4=128

3X-8 = 128-4

= 124

3X = 124+8

= 132

X = 132÷3

= 44

So Rams mark = 44

Shyams mark = 44-8

= 36

Anils mark = 44+4

=48

Total mark =44+36+48

= 128
