Exercise 4C Q18 | Solving Competition Score Problems | Think New Syllabus 8th Edition Oxford

#VectorVictory #OxfordMath #Exercise4C #Class8Math #WordProblems #MathShortcuts #NewSyllabusMathematics #Integers Master the logic behind competitive exam scoring! In this Vector Victory tutorial, we break down Question 18 from Exercise 4C in the Think New Syllabus Mathematics 8th Edition. This problem is a classic example of how to use integers to solve real-world scenarios involving "negative marking." What you will learn in this video: Part (i): How to calculate the number of correct answers when the total questions and total marks are known (Nadia’s Case). Part (ii): How to find possible combinations of correct and wrong answers to result in a negative final score (Waseem’s Case). Question Solved in This Video: Question 18: There are 20 questions in a mathematics competition. A correct answer is awarded 2 marks, but a wrong answer is awarded -1 mark. If no answer is given, 0 marks will be awarded. (i) Nadia answered a total of 14 questions and scored 10 marks. How many questions did she answer correctly? (ii) Waseem scored -8 marks for the competition. He has forgotten how many questions he answered. Give an example of the number of correct answers and the number of wrong answers that he might have obtained. Quick Tips for this Exercise: Let x be the number of correct answers. Use the formula: (Correct \times 2) + (Wrong \times -1) = Total Marks. Always check if your total number of questions exceeds the limit (20).
