Let the number of correct answers be M.
The number of incorrect answers will be 94 – M.
⇒ 4 × M – (94 – M) = 141
⇒ 5M = 235
⇒ M = 47 [Correct number of questions]
So, the number of wrongly answered = 94 - M
⇒ 94 - 47 = 47
∴ The number of wrongly answered questions is 47.Last updated on Jul 15, 2025
