Answer 1

The Correct Option is B

To find the central angle for women employees, we use the formula for the central angle in a pie chart (circle graph):
\[ \text{Central Angle} = \frac{\text{Number of women employees}}{\text{Total number of employees}} \times 360^\circ \] Let the total number of employees in company B be \( N \), and the number of women employees be \( W \). The central angle for the women employees is given by: \[ \text{Central Angle} = \frac{W}{N} \times 360^\circ \] Using the data from the image you provided, the percentage of women employees in company B is approximately \( 18 %\). Thus, the central angle is:
\[ \text{Central Angle} = \frac{18}{100} \times 360^\circ = 64.8^\circ \] Therefore, the correct answer is (2) 64.8°.

Answer 2

To find the difference in the number of women employees between company D and company E, we need to subtract the number of women employees in company E from those in company D. The formula is: \[ \text{Difference} = \text{Number of women employees in company D} - \text{Number of women employees in company E} \] Using the data from the image you provided, the number of women employees in company D is 856 and in company E is 526. So, the difference is: \[ \text{Difference} = 856 - 526 = 330 \] Thus, the correct answer is (3) 330.

Answer 3

To find the total number of women employees in company A and company D together, we simply add the number of women employees in both companies. From the image, we can see the following:
- Number of women employees in company A: 712
- Number of women employees in company D: 740
Thus, the total number of women employees in company A and D together is:
\[ 712 + 740 = 1452 \] Therefore, the correct answer is (4) 1452.

Answer 4

We are given that the ratio of women employees to men employees in company F is 9:8. Let the number of women employees be \( 9x \) and the number of men employees be \( 8x \), where \( x \) is the constant.
The total number of employees in company F is the sum of women and men employees:
\[ \text{Total employees} = 9x + 8x = 17x \] From the image data, we know the total number of employees in company F is 561. Thus, we have: \[ 17x = 561 \] Solving for \( x \): \[ x = \frac{561}{17} = 33 \] Now, the total number of employees is: \[ \text{Total employees} = 17 \times 33 = 561 \] Therefore, the correct answer is (1) 561.

Answer 5

We are given that the total number of women employees in company C is 400 and in company A is 600. To find the percentage less, we use the following formula: \[ \text{Percentage Less} = \frac{\text{Difference in number of employees}}{\text{Number of women employees in company A}} \times 100 \] The difference in the number of employees between company A and company C is: \[ 600 - 400 = 200 \] Now, substitute this difference into the formula: \[ \text{Percentage Less} = \frac{200}{600} \times 100 = 33.33% \] Thus, the total number of women employees in company C is approximately 25% less than in company A. Therefore, the correct answer is (2) 25%.
