Answer:
The answer is given below :
No. of correct answers = 25
So, marks secured = 25 × 4 = 100
Let, he did x no. of incorrect answers.
So, marks be cut = x × (-2) = -2x
Thus,
100 - 2x = 68
=> 2x = 100 - 68
=> 2x = 32
=> x = 16
So, Rohit did 16 incorrect answers and in total he attempted (25 + 16) = 41 questions.
hope it helps
