Question

Wheat production of a country over a number of years is shown. Which year recorded highest percent reduction in production over the previous year?

The correct answer is
2004

To determine the year with the highest percent reduction in wheat production over the previous year, we need to calculate the percentage decrease for each year compared to its preceding year.

  1. From the image:
    • 2000: 50 metric tons
    • 2001: 45 metric tons
    • 2002: 40 metric tons
    • 2003: 35 metric tons
    • 2004: 30 metric tons
  2. Calculate the percentage reduction for each year:
    1. 2001: \(\frac{50 - 45}{50} \times 100 = 10\%\)
    2. 2002: \(\frac{45 - 40}{45} \times 100 = 11.11\%\)
    3. 2003: \(\frac{40 - 35}{40} \times 100 = 12.5\%\)
    4. 2004: \(\frac{35 - 30}{35} \times 100 = 14.29\%\)
  3. Identify the year with the highest reduction:
    • 2004 shows the highest percentage reduction of 14.29% over the previous year.

Therefore, the year 2004 recorded the highest percent reduction in wheat production over the previous year.
