Question

Pankaj scored 15marks fewer than Charu&Charu scored 5marks more than Kanta.In total they scored 112marks.what is the mark of Kantha?

Answer 1

Let Charu's marks be x.
Then, Kantha's marks will be (x-5).
Then, Pankaj's marks will be (x+15)
So the equation will be,
x+x+15+x-5=112
3x+10=112
3x=112-10
3x=102
x=102/3=34
Therefore,
marks of Charu is 34.
marks of Kantha is 29.
marks of Pankaj is 49.

Answer 2

Let Kantha's mark be x
ATQ  Charus's mark= x+5
         Pankaj's mark= (x+5) - 15
Total marks  x+ (x+5) + (x+5) - 15= 112
                 ⇒ 3x - 5 =112
                 ⇒ 3x = 117
                 ⇒   x = 39
Kantha's mark is 39
