Question

.In a quiz each student is required to answer 40 questions. 5 marks are given for every correct answer and 3 marks are deduced for every wrong answer. If Raj answered 35 questions correctly and Rahul answered 32 questions correctly of all the attempted questions, what is the difference in the total marks obtained by them?​

Answer 1

Answer:

24

Explanation:

Raj's total marks is 160 & Rahul's total mark is 136

So, the difference is 24

Answer 2

Marks given for one correct answer = 5

So, marks given for 10 correct answers 

= 5 X 10 = 50

Radhika's score = 30

Marks obtained for incorrect answer

= 30- 50 = -20

Marks given for one incorrect answer 

= (-2)

Therefore, number of incorrect answers

= (−20)÷(−2)=10
