Question

In a Math test (+2) marks are given for every correct answer and (-1) mark is given for every incorrect answer. Zayan gets only 12 of his answers correct out of 18 questions on the test. What will be his score if he attempted all the questions?

Answer 1

Answer:
18/36 (1/2) or 50%

Explanation:
You get 2 marks for each correct answer and a mark is deducted for each incorrect answer. If Zayan had got every answer correct, he would have gotten 36 marks, therefore the maximum mark possible is 36. Zayan only got 12 answers correct, so he gets 24 marks as 12 · 2 = 24. He answered every question and got 6 wrong, so 6 marks should be deducted. His score, therefore, is 18 out of 36, as 24 - 6 = 18. You can also simplify 18/36 to 1/2 and also convert it to 50%.

Hope this helps! Brainliest is appreciated. :D

Answer 2

The score in the test based on the equation illustrated is 18.

How to compute the value?

Let the equation used be:

= 2c -1w

where c = correct answers

w = wrong answers

Therefore, he got 12 correct and 6 wrong. This will be:

2c - w

= 2(12) -6

= 24 - 6

= 18

In conclusion, the score is 18.
