Question

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

(1) Total cost of the flat.

(2) Expenditure incurred on labour.

Answer 1

(1) Expenditure incurred on cement = \(\frac{Central\,angle\,of\,the\,sector\times\,Total\,cost}{360^\circ}\)

Total cost of the flat = \(\frac{360^\circ\times112500}{75^\circ}=540000\) rupees

(2) Expenditure incurred on labor = \(\frac{Central\,angle\,of\,the\,sector\times\,Total\,cost}{360^\circ}\) = \(\frac{100^\circ\times540000}{360^\circ}\) 

= 150000 rupees
