Answer:
57
Step-by-step explanation:
Maximum score: 15 x 5 = 75
Number of correct answers: 12
Marks allotted for correct answers: 5
Total marks for correct answers: 12 x 5 = 60
Number of incorrect answers: 3
Marks allotted for incorrect answers: ( -1 )
Total marks allotted for incorrect answers: 3 x ( -1 ) = (-3)
Total marks for correct answers: 12 x 5 = 60
Total marks allotted for incorrect answers: 3 x ( -1 ) = (-3)
∴ Score = 60 + ( -3 )
60 + ( -3 )
=> 60 - 3
=> 57 ( since integer with greater absolute value is 60 )
∴ Vishesh's score is 57/75
