Question

Different expenditures incurred on the construction of a building were shown by a pie diagram. The expenditure of Rs. 45,000 on cement was shown by a sector of central angle of 75°. What was the total expenditure of the construction? 

(A) 2,16,000 

(B) 3,60,000 

(C) 4,50,000 

(D) 7,50,000

Answer 1

(A) 2,16,000

Measure of the central angle = (Expenditure of cement) / (Total expenditure ) x 360^∘

∴ Total expenditure = (45000 x 360^∘)/ 75^∘ = Rs. 2,16,000
