answer is 39
Step-by-step explanation:
total number of question is 50
one right answer rewarded 2 marks
one wrong answer deducted 1 marks
if 41 question was attempted
where 2 question answered incorrectly =-2
and 39 question answered correctly=78
total score is 78-2=76
therefore

Answer:
Step-by-step explanation:
Let number of correct answers be X
No of wrong answers be y
Then 2x -y =76 eq1 ( total marks gained )
And X+Y = 50 eq2 (No of questions )
Solving both eqs1&2 we get X= 42
Y=8
No of correct answers are 42
