Question

pankaj obtain 15 marks less than charu. charu have obtain 5 marks more than rohan and the total marks of the student is a 113 so rohan how much marks obtain? please answet step by step

Answer 1

let the total marks obtained by Rohan be x.
marks obtained by Charu = x+5
marks obtained by Pankaj = x+5 -15 = x-10
total marks = 113

a/q      (x) + (x+5) + (x-10) = 113
        ⇒  3x - 5= 113
        ⇒   3x = 113+5
        ⇒  x = 118/3
         ∴  x = 39.33

so, total marks obtained by Rohan is 39.33 approx.

Answer 2

Answer:

Step-by-step explanation:

Given :-

Pankaj obtain 15 marks less than Charu.

Charu have obtain 5 marks more than Rohan

Total marks of the student = 113

To Find :-

Marks Obtained by Rohan.

Solution :-

let the total marks obtained by Rohan be x.

Marks obtained by Charu = x + 5

Marks obtained by Pankaj = x + 5 - 15 = x - 10

According to Question.

⇒ (x) + (x+5) + (x-10) = 113

⇒ 3x - 5= 113

⇒ 3x = 113+5

⇒  x = 118/3

⇒  x = 39.33

Hence, the marks obtained by Rohan is 39.33 approx.
