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

Correct option is D

Given:

Wheat production (in metric tons) from 2000 to 2004:

• 2000: 50
• 2001: 45
• 2002: 40
• 2003: 35
• 2004: 30

We are to find the year with the highest percentage reduction in production over the previous year.

Concept Used:
​$$\text{Percentage reduction} = \frac{\text{Previous year} - \text{Current year}}{\text{Previous year}} \times 100$$​​

Solution:

​$$\begin{aligned}\text{2000 to 2001:} &\quad \frac{50 - 45}{50} \times 100 = 10\% \\\ \\\text{2001 to 2002:} &\quad \frac{45 - 40}{45} \times 100 = 11.11\% \\\ \\\text{2002 to 2003:} &\quad \frac{40 - 35}{40} \times 100 = 12.5\% \\\ \\\text{2003 to 2004:} &\quad \frac{35 - 30}{35} \times 100 = 14.29\%\end{aligned}$$​​

So, the highest percentage reduction occurred in 2004.

Correct Option: (D) 2004
