Question

Aidan is doing a multiple choice test with 20 questions he scores 3 marks for a correct answer and loses 1 mark if the answer is incorrect he answered all questions and scored 40 marks how many we questions were correct

Answer 1

Answer: 13.3 repeating is what I got see if it make sense according to my work

Step-by-step explanation: 20x3=60, and one mark per wrong answer, so 60-40=20 wrong. So, 40 divided by 3=13.3 repeating

Answer 2

Answer: 10 answers correct and 10 answers incorrect

Explanation:

60 is the highest total assuming every one was correct

20 is the lowest total assuming every one was incorrect

40 is the middle meaning he got half write half wrong

Half of 20 is (10) (10 x 3 = 30 ) + ( 10 x 1 = 10 ) 30 + 10 = 40
