Let total questions be x
correct answer = 4x/5
out of 41, 37 are correct
remaining questions are x-41
out of these correct answers are x-41+8 = x-33
4x/5 = 37+x-33
i.e. 4x/5 = x+4
i.e. 4x = 5x+20
i.e. 5x-4x = 20
i.e. x = 20
total questions are 20
correct answer = 4x/5
out of 41, 37 are correct
remaining questions are x-41
out of these correct answers are x-41+8 = x-33
4x/5 = 37+x-33
i.e. 4x/5 = x+4
i.e. 4x = 5x+20
i.e. 5x-4x = 20
i.e. x = 20
total questions are 20
