Riya gets correct solutions =9
And incorrect =11
A.C.T
Correct solution marks =6
Incorrect solution marks =-2
Therefore, total marks = 9 multiplied by 6 =54
=11 multiplied by 2 =22
=54-22
=32
Thus, Riya total score =32(answer)
Sumit got marks =36
In that 6 are correct only (because 6 marks are awarded for 1 correct question )
Thus, he had attempted incorrect =20-6 =14 (answer )
