Question

The annual profit chart of a company is given below. Which option is the correct statement? 

• A. The percentage increase between \(1965\) and \(1970\) is more than \(75%\).
• B. The percentage decrease between \(1985\) and \(1990\) is less than \(27%\).
• C. The percentage increase between \(2005\) and \(2010\) is more than \(100%\).
• D. The percentage decrease between \(2015\) and \(2020\) is less than \(10%\).

Hint:

For percentage changes, use \( \frac{\text{Final} - \text{Initial}}{\text{Initial}} \times 100 \).

Answer 1

The Correct Option is A

Step 1: Calculate profits in \(1965\) and \(1970\): \(40\) and \(90\), respectively.
Step 2: Percentage increase \(= \frac{90-40}{40} \times 100 = 125%\). Thus, it is more than \(75%\).
Step 3: Verify other statements similarly. Only \(A\) is correct.
