Question

The pie-chart given in the following represents the expenditure on different items in constructing a flat in Delhi. If the expenditure incurred on cement is Rs 112500, find the following:


(i) Total cost of the flat.
(ii) Expenditure incurred on labour.

Solution

(i) Expenditure incurred on cement  =

\[\frac{\text{ Central angle of the corresponding sector } \times\text{ Total cost }}{360^\circ}\]
Total cost of the flat = \[\frac{360^\circ \times 112500}{75^\circ} =\text{ Rs }540000\]
(ii) Expenditure incurred on labour = \[\frac{\text{ Central angle of labour sector }\times\text{ Total cost }}{360^\circ}\]\[= \frac{100^\circ \times 540000}{360^\circ} =\text{ Rs }150000\]
  Is there an error in this question or solution?
