Final answer:
Mohan's score can be calculated by subtracting the number of incorrect answers from the number of correct ones, resulting in a score of -2. However, if negative scoring is not allowed, his score may be zero.
Step-by-step explanation:
This problem can be solved by giving a point for every correct answer and subtracting a point for every incorrect one. In this scenario, Mohan got 4 correct answers and 6 incorrect ones. Therefore, we can calculate his score as follows:
Score = (Number of correct responses) - (Number of incorrect responses).
When we substitute in the values, we get:
Score = (4) - (6) = -2.
So, Mohan's score is -2. This means he got more answers incorrect than correct ones. In some scoring systems, negative scores may not be allowed and the lowest score may be set at zero. Depending on the rules established, his score could possibly be zero rather than -2.
