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

Hope this helps!
