Question

The line graph shows monthly closing stock prices (in Rs.) of Company X for Jan-Apr 2015: Jan = 100, Feb = 120, Mar = 110, Apr = 130. What is the percentage increase from Jan to Apr?

• A. 20%
• B. 25%
• C. 30%
• D. 35%

Hint:

For line graph percentage changes, use $\left(\dfrac{\text{Final} - \text{Initial}}{\text{Initial}}\right) \times 100$.

Answer 1

The Correct Option is C

- Step 1: Prices: Jan = 100, Apr = 130.
- Step 2: Increase = $130 - 100 = 30$.
- Step 3: Percentage increase = $\left(\dfrac{30}{100}\right) \times 100 = 30%$.
- Step 4: Verify: $100 \times 1.3 = 130$.
- Step 5: Check options: Option (3) is 30%, which matches.
- Step 6: Ensure correct months.
