Step 1: Identifying the production values.
Let the production of Ludo in 1992 be \( P_{1992} \) and in 1994 be \( P_{1994} \).
Step 2: Percentage decrease formula.
\[ {Percentage Decrease} = \frac{P_{1992} - P_{1994}}{P_{1992}} \times 100 \]
Step 3: Substituting values and calculating.
Using the given values, we get: \[ {Percentage Decrease} = \frac{X - Y}{X} \times 100 \] Computing the values, we find that the drop is 10%. Thus, the correct answer is (D) \( 10 \).
