What will Hema's score be in a class test containing 10 questions? 5 marks are awarded for every correct answer, (-2) marks are awarded for every incorrect answer, and 0 marks for each question not attempted. Hema got 2 correct and 5 incorrect answers.

To calculate Hema's score in the class test, we can use the given information:

She gets 5 marks for every correct answer. 

She loses 2 marks for every incorrect answer.

She receives 0 marks for each question not attempted.

Now, let's calculate her score based on the information provided:

Step 1: 

For the 2 correct answers, she earns: 

2 correct answers $\times$ 5 marks per correct answer = 10 marks

Step 2: 

For the 5 incorrect answers, she loses: 

5 incorrect answers $\times$ 2 marks lost per incorrect answer = -10 marks 

Step 3: 

For the 3 unattempted questions, she neither loses nor gains.

So, it is 0 for the 3 unattempted questions.

Step 4: 

Now, we can calculate her total score by adding up the marks earned and lost:

Total score = Marks earned - Marks lost

Total score = 10 marks - 10 marks = 0 marks

So, Hema's score in the class test is 0 marks.
