Question

In a test,5 Mark are given for every correct answer and (_2) marks are given for every wrong answer.Sudhir answer all questions and scored 30 marks though he got 10 correct answer.Find the total number of questions in the test.

Answer 1

Total correct answers = 10
Each correct answer = +5
Each incorrect answer = -2

therefore, total marks Sudhir would have scored without negative marking = 10*5 = 50

Marks Sudhir scored = 30

therefore, marks deducted due to negative marking = 50 - 30 = 20

no. of incorrect answers = 20/2 = 10

therefore, total number of questions = no. of incorrect answers + no. of correct answers

= 10 + 10
= 20
