Roshan has solved 245 questions in an examination. If he got only '0' marks, then how many questions were wrong when one mark is given for each one correct answer and 2/3 mark is subtracted on each wrong answer.
X - number of correct answers X - (245 -X)*(2/3) = 0 X = 245*(2/3) - X(2/3) X = 245*(2/3)*(3/5) = 98 Correct answers and 147 wrong answers.
