We start by stating the given contingency table data clearly so we know what values are known and what must be found.

- Mining row shows: in Investor A column the value is X, in Investor B column is 10, in Investor C column is 21, and the row total is Y.
- Forestry row shows: Investor A = 15, Investor B = 5, Investor C = 6, row total = 26.
- Eco-Tourism row shows: Investor A = 10, Investor B = 15, Investor C = 4, row total = 29.
- Column totals (across industries) are shown as: for Investor A total = Z, Investor B total = 31, Investor C total = 108, and the grand total (bottom-right) = 108 (interpreted from the given layout as the overall total in the C column). Note: there is an ambiguity in the way the totals are labeled, but we proceed with the typical interpretation that the column totals are at the bottom of each investor column and the row totals are at the end of each row.

First, use the Investor A column total to solve for X:
- Investor A column total is Z, and the entries in that column are X (Mining), 15 (Forestry), and 10 (Eco-Tourism).
- Therefore, X + 15 + 10 = Z, so X + 25 = Z.
- The bottom total shown for Investor A is 30, so Z = 30.
- Solving X + 25 = 30 gives X = 5.

Thus, based on the column total given for Investor A, the missing value X would be 5.

Next, check consistency with the Mining row total Y:
- Mining row total Y is X + 10 + 21 = X + 31.
- With X = 5, Y = 5 + 31 = 36.

Now examine the Investor B column total to see if it aligns with the provided 31:
- Investor B column entries are 10 (Mining), 5 (Forestry), 15 (Eco-Tourism).
- Sum = 10 + 5 + 15 = 30.
- This would imply the Investor B column total should be 30, not 31.

At this point, we observe an inconsistency in the provided totals: the Investor A column total leads to X = 5, and the derived row total for Mining is Y = 36, but the Investor B column total given as 31 does not match the computed sum of its entries (30).

Since the problem statement provides specific totals (30 for Investor A, 31 for Investor B, 108 for Investor C, and 108 as a grand total in some formulations), resolving all values self-consistently would require reconciling these discrepancies. With the data as given and following the standard method of using column totals to find missing cells, the result for X is 5, and this leads to a mismatch in the Investor B column total if we hold all other numbers fixed.

In summary, using the standard approach of equating the Investor A column sum to Z yields X = 5. However, this creates a discrepancy with the Investor B column total, indicating an inconsistency in the provided totals for the table. The steps above show exactly how X = 5 is obtained and where the inconsistency arises.

You are given the following partially completed contingency table. Find the missing value for X. Investor A Investor B Investor C TOTAL Mining X 10 21 Y Forestry 15 5 6 26 Eco-Tourism 10 15 4 29 TOTAL Z 30 31 108
