To determine the percentage increase in steel output, we can follow these steps:
1. Identify the initial and final outputs:
- Initial output (first year): 150 tons
- Final output (second year): 180 tons
2. Calculate the increase in output:
- Increase = Final output - Initial output
- Increase = 180 tons - 150 tons
- Increase = 30 tons
3. Calculate the percentage increase:
- Percentage Increase = (Increase / Initial output) × 100
- Percentage Increase = (30 tons / 150 tons) × 100
- Percentage Increase = 0.2 × 100
- Percentage Increase = 20%
4. Determine the correct answer from the given options:
- The options provided are:
- A. 17%
- B. 20%
- C. 30%
- D. 50%
- E. 75%
- Since the calculated percentage increase is 20%, the correct answer is:
B. 20%
So, the percentage increase in the output is 20%.
