If he answered 3 questions correctly, then the number of questions is got wrong is 7 and the number of questions that he did not attempt is 5.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
In a class test of 15 questions, (+4) marks are given for every correct answer, (– 2) marks are given for every incorrect answer, and 0 marks are given for questions that are not attempted. Punit scored (– 2) marks.
If he answered 3 questions correctly, then the number of the question are got wrong and the number of the question that he did not attempt.
Let x be the correct question and y be the incorrect question, z be the number of questions that he did not attempt, and A be the number of the total score. Then we have
4x – 2z = A
x + y + z = 15
If A = -2 and x = 3, then we have
4 × 3 – 2z = -2
12 + 2 = 2z
z = 7
Then the value of y will be
3 + y + 7 = 15
y = 5

Another is 2 I hope this helped
Answer:
The digit 4 should be in the thousand position in the number sought;
Examples
9.30<u>4</u>,
9.00<u>4</u>
Step-by-step explanation:
Here, we are required to consider decimal places of numbers
The digit 4 in the number 3.8463 is in the hundredth position
That is 0.04
We are asked to look for the number with a digit 4 that has the same value as 
the digit 4 in 3.8463
That is
Therefore, the digit 4 in the number sought should be in the thousandth position, that is 0.004
Example includes 9.304 or 9.004.
