Solving Problems

Romila appeared for a maths exam. She was given 100 problems to solve. She tried to solve all of them correctly but some of them went wrong. Any how she scored 85.

Her score was calculated by subtracting two times the number of wrong answer from the number of correct answers.

Can you tell how many problems she solved correctly?

    1. sorry , i can’t understand about the correct ans, 95 . we already got the ans
      95 and 5 then wat is that 95 ???????????? explain pls..

      1. As per given question
        x+y=100
        x-2y=85
        after solving both equations we get y=5
        and x=95
        so correct ans are 95
        score was calculated by subtracting two times the number of wrong answer from the number of correct answers i.e
        no. of wrong answer appeared is 5*2=10 i.e as is 95-10=85
