Answer 2

Answer:

The score of Mohan = 22 marks

Step-by-step explanation:

Given:

• In a class test containing 20 question, every correct answer is awarded 5 marks, every, incorrect answer is awarded (-2) marks and 0 marks are for every question not attempted.
• A student get 6 questions right, 4 questions wrong and leave 10 question unattempted.

To find:

• What is his score?

Solution:

If a student gives x right questions, y wrong questions and z are questions which are not attempted, then his total marks would be 5x + (-2)y + z × 0

Here, we know that a student get 6 questions right which means 5 × 6, 4 questions wrong that is (-2) × 4 and leave 10 question unattempted i.e, 10 × 0.

Now, we will combine them and solve and can easily find out his score.

Let's find out...

• His score = 5 × 6 + - 2 × 4 + 10 × 0
• His score = 30 + - 8 + 0
• His score = 30 - 8
• His score = 22

∴ He scored 22 marks.
