Solving Problems

Email This Post Email This Post

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?

    x+y=100
    x-2y=85
    solving both equations we get y=5
    and x=95
    so correct ans are 95
