The table below lists wheat production (in thousand metric tonnes, TMT) across five agricultural zones in 2024:
• Zone A: $160\text{ TMT}$
• Zone B: $110\text{ TMT}$
• Zone C: $195\text{ TMT}$
• Zone D: $75\text{ TMT}$
• Zone E: $140\text{ TMT}$
The percentage contribution of Zone C to the total wheat production of all five zones combined in 2024 was ________ % (round off to 1 decimal place).
Answer Key:
28.7
Step-by-Step Solution & Explanation
1. Compute total wheat production across all five zones in 2024:
$\text{Total} = 160 + 110 + 195 + 75 + 140 = 680\text{ TMT}$
2. Production of Zone C $= 195\text{ TMT}$.
3. Percentage contribution:
$\text{Percentage} = \frac{195}{680} \times 100\% = \frac{19500}{680} \approx 28.676\% \approx 28.7\%$
