Question

In a quiz with 10 questions, a player scores +2 points for each correct answer and –2 points

for each incorrect answer. What is the score of Tom if he answers 6 questions correctly?​

Answer 1

Marks for correct = 2 * 6 = 12
Negative marking = 4 * -2 = -8
Total = 12-8 = 4
Final = 4 points

Answer 2

Answer:

$\sf \green {\therefore \: Tom's \: score = 4}$

Step-by-step explanation:

Total no. of questions = 10

Correct answer = +2

Incorrect answer = -2

No. of correct answer = 6

No. of incorrect answer = 10 - 6 = 4

Tom's score = 2 × 6 + ( -2 ) × 4

= 12 + ( -8 ) = 4
