Question

Using the same table, what is the percentage increase in sales of Product B from January to February?

• A. 25%
  
• B. 33.33%
  
• C. 40%
  
• D. 50%
  

Hint:

For percentage increase, use the formula $\left( \frac{\text{New} - \text{Old}}{\text{Old}} \right) \times 100$ and simplify fractions.

Answer 1

The Correct Option is B

- Step 1: Extract data. Sales of Product B: January = 30, February = 40 (in thousands).
- Step 2: Calculate absolute increase. Increase = $40 - 30 = 10$.
- Step 3: Compute percentage increase. Formula: $\text{Percentage increase} = \left( \frac{\text{New value} - \text{Old value}}{\text{Old value}} \right) \times 100 = \left( \frac{40 - 30}{30} \right) \times 100 = \frac{10}{30} \times 100 = 33.33%$.
- Step 4: Simplify calculation. $\frac{10}{30} = \frac{1}{3}$, and $\frac{1}{3} \times 100 \approx 33.33$.
- Step 5: Compare with options. Options: (1) 25%, (2) 33.33%, (3) 40%, (4) 50%. The result matches 33.33%.
- Step 6: Verify. Alternative: $30 \times \frac{4}{3} = 40$, confirming 33.33% increase.
- Step 7: Conclusion. Option (2) is correct.
