\(Percentage-Decrease = \frac{Finial - Initial }{Initial} *100\)

\(=\frac{13000-18000}{18000}*100 = -\frac{5}{18}*100=-5.55*5=-27.75\)

Hello, I tried this solution;

Quote:
Since the question is asking us the percentage of decrease from the total (18,000).
Therefore, 18,000(TOTAL UNITS) - 13,000(DECREASED UNITS) = 5000 units.

5000*100 = 500,000;
500,000 / 18,000 (total units). = 27.778

Maybe we can do this simplified removing some 0's.
50*1 = 50
50/180 = 2.7778. and just add up 0's again by moving the dot.

Answer E.

Is this correct?

Solution



Given
In this question, we are given that
    • From 1908 to 1912, the total production capacity of industry W declined from 18,000 units per year to 13,000 units per year

To find
We need to determine
    • The approximate percent decrease in total production capacity for industry W during this time period

Approach and Working out
Production capacity at the beginning = 18k units
Production capacity at the end = 13k units
    • Hence, percentage reduction in production capacity = (18k – 13k)/18k * 100 = 5/18 * 100 = 27.78%

Thus, option E is the correct answer.

Correct Answer: Option E
