1. The problem asks about the effect of a reduction in the cost of transport, which is initially 12000. 2. To analyze this, we need to know the amount or percentage by which the cost is reduced. 3. The formula for the new cost after reduction is: $$\text{New Cost} = \text{Original Cost} - \text{Reduction Amount}$$ 4. If the reduction is given as a percentage $r\%$, then: $$\text{Reduction Amount} = \frac{r}{100} \times 12000$$ 5. Without the exact reduction value, we cannot compute the new cost. 6. Please provide the reduction amount or percentage to proceed with the calculation.
