The table below provides details regarding the number of men and women working at five distinct corporations (V, W, X, Y, and Z), along with the proportion of total personnel (men + women) who received a promotion at each corporation. Review the dataset to answer the question that follows.

Corporation	Men	Women	% of personnel promoted
V	400	350	40%
W	260	100	80%
X	340	410	60%
Y	200	300	80%
Z	240	360	50%

Note: The total staff size at any corporation is the sum of the men and women working there.

If the number of men who received a promotion in Z is equal to the number of men working at Y, and the number of women who received a promotion in X is 60% higher than the number of women promoted in Z, then the number of men who received a promotion in X and Z combined represents what percentage of the total staff at Y?

The correct option is 98%.

Step 1: Understand the dataset given in the table.

Let's calculate the total staff and the number of promoted personnel for each relevant corporation using the table provided:

Corporation V:
Total staff = 400 (Men) + 350 (Women) = 750

Corporation W:
Total staff = 260 (Men) + 100 (Women) = 360

Corporation X:
Total staff = 340 (Men) + 410 (Women) = 750
Percentage of personnel promoted = 60%
Total promoted personnel in X = 60% of 750 = $\frac{60}{100}✕750=450$

Corporation Y:
Total staff at Y = 200 (Men) + 300 (Women) = 500
Number of men working at Y = 200

Corporation Z:
Total staff = 240 (Men) + 360 (Women) = 600
Percentage of personnel promoted = 50%
Total promoted personnel in Z = 50% of 600 = $\frac{50}{100}✕600=300$

Step 2: Find the number of men promoted in Z.

According to the given condition, the number of men who received a promotion in Z is equal to the number of men working at Y.
From the table, the number of men working at Y = 200.
Therefore, Men promoted in Z = 200.

Step 3: Find the number of women promoted in Z and in X.

Since the total promoted personnel in Z is 300:
Women promoted in Z = Total promoted in Z - Men promoted in Z
Women promoted in Z = 300 - 200 = 100.

The problem states that the number of women promoted in X is 60% higher than the number of women promoted in Z:
Women promoted in X = 100 + (60% of 100) = 100 + 60 = 160.

Step 4: Find the number of men promoted in X.

Since total promoted personnel in X = 450:
Men promoted in X = Total promoted in X - Women promoted in X
Men promoted in X = 450 - 160 = 290.

Step 5: Calculate the combined men promoted in X and Z as a percentage of the total staff at Y.

Combined men promoted in X and Z = 290 + 200 = 490.

Total staff at Y = 500.

Required percentage = $\left(\frac{490}{500}\right)✕100=98\%$

Thus, the number of men who received a promotion in X and Z combined represents 98% of the total staff at Y.
