Consider the following for the next three (03) items that follow:<br>Study the following Pie Charts:<br>
- A. 11°
- B. 13°
- C. 15° ✓
- D. 23°
Correct Answer: C. 15°
Explanation
The original number of Kutcha houses is \frac{40^{\circ}}{360^{\circ}} \times 120000 = 13333. Adding 5000 gives 18333 houses. Assuming the total base of 120,000 remains constant for the pie chart scale, the new angle is \frac{18333}{120000} \times 360^{\circ} \approx 55^{\circ}. The change in angle is 55^{\circ} - 40^{\circ} = 15^{\circ}.
