Answer 1

Answer:

Therefore Sangays Mark is 20.

Step-by-step explanation:                            

Total mark - 100

Shushi Mark - 10-X

Dikkis mark= X

Sangays Mark- X+10-X

Sangays Mark =  X+10-X+X=100

                            2X-X+10=100

                            X+10=100

                            X=90

 Therefore Shusis mark=10-90

90-10=80

Sangays Mark- X+80=100

                         X=20
