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 answers from the number of correct answers.

Can you tell how many problems she solved correctly?

  1. 85=100-2*y. Where y is no of wrong answers.

    y=30. So the no of correct answers she answered is 70.

  2. pls solve this question
    25 * 25 = 625
    how 2 5
    & 2*3=6
    then 625
