Answer 1

let kantas marks be X
then charus marks= X+5

sum of their marks =112
X+X+5+X-10=112
3X-5=112
3X=117
X=39 
kanta got 39 marks

Answer 2

Let charu's marks be x, Then pankaj marks=x-15 And kanta's marks = x+5 Now, x+x+5+x-15=112 3x+20=112 3x=112-10 3x=102 X=102/3=34 Charu's marks 34 Kanta marks 34 +5=39
