Answer 1

Using the information given, we calculated that 3150 people attended the XYZ company's exam for the post of senior officer, based on the fact that 10% of the attendees were selected and the number of selected candidates was 315.

Step-by-step explanation:

To determine how many people attended the exam, we need to use the information provided about the percentage of candidates who were selected. Since 10% of the total candidates were selected and the number of selects is given as 315, we can set up the following equation:

0.10 × Total Candidates = 315

To find the number of Total Candidates, we divide both sides of the equation by 0.10:

Total Candidates = 315 / 0.10

Total Candidates = 3150

Therefore, 3150 people attended the exam.

Answer 2

To find the number of people who attended the exam, you need to find the total number of candidates who were selected for the post of senior officer. From the given information, you can set up an equation and solve for the number of people who attended the exam, which is 15750.

Step-by-step explanation:

To find the number of people who attended the exam, you need to find the total number of candidates who were selected for the post of senior officer.

Let's assume that the total number of candidates who attended the exam is 'x'.

From the given information, 20% of the total candidates were qualified, which means 0.2x candidates qualified for the post.

Out of the qualified candidates, 10% were selected. So, 0.1(0.2x) candidates were selected for the post.

According to the question, the number of selects for the post of senior officer was 315.

Therefore, the equation is 0.1(0.2x) = 315.

Solving this equation, we get x = 15750.

So, 15750 people attended the exam.
