Question

The following pie chart shows the distribution of a sum of 15 million, which was spent by a contractor as part of the road rubberization projects of the state government.




NOTE - The values inside the pie chart denote the angle subtended by the corresponding sector at the centre.

The amount spent on bitumen and equipment exceeds the amount spent on rubber alone by

• A. 0.375 million
• B. 3% of the total expenditure
• C. 7.5% of the total expenditure
• D. 1.125 million

Answer 1

The correct option is A 0.375 million

Total subtended angle at the centre = 360°
Which means that 3.6° = 1%
% share of rubber alone $=\frac{108}{3.6}=30\%$
% share of bitumen and equipments $\frac{\left(}{54+63}=32.5\%$
Difference$=\frac{\left(}{32.5-30}\times 15000000$
= Rs. 37,5000 = 0.375 million
