Question

in an examination 3 marks are given for correct answers 2 marks are deducted for incorrect answers zero marks for not attending if Mira scores 100 marks on attempting 60 correct questions find the total questions in the examination

Answer 1

Answer:

100 questions

Step-by-step explanation:

This is a semultennous equation question.

She got 100 marks after attempting 60 * 3 possible pass marks = 180 marks. But she got 100 marsk instead which means she lost 80 marks with 2 marks each which is 40 questions wrong. Let correct answered questions be x and wrong questions be y

3x = 180.                              2y = 80

x. =  60                                   y = 40
