Study the given pie chart and answer the question that follows.

The given pie chart represents the total expenditure of ₹54,000 on different items in constructing a flat in a town.

The approximate percentage of the total expenditure on steel and cement is:

Correct option is B

Given:

Total expenditure = ₹54,000

The angles in the pie chart:

Steel = 45°

Cement = 75°

Formula Used:

Percentage expenditure on item = $$\left(\frac{\text{Angle of item}}{360^\circ}\right) \times 100$$​

Solution:

Total angle in a pie chart = 360°

Percentage on Steel =$$\left(\frac{45^\circ}{360^\circ}\right) \times 100 = 12.5\%$$​

Percentage on Cement $$= \left(\frac{75^\circ}{360^\circ}\right) \times 100 = 20.83\%$$​

Total percentage on Steel and Cement:

Total Percentage =12.5% + 20.83% = 33.33%$$\approx 33\%$$​

Thus, the approximate percentage of the total expenditure on steel and cement is 33%.
