Question

The angle subtended by blue portion at the center of following pie-chart is.

• A. ${227}^0$
• B. ${234}^0$
• C. ${254}^0$

Answer 1

The correct option is B ${234}^0$

We know that total angle subtended by the pie-chart at its centre is ${360}^0$
Blue portion comprises of 65% of the total area of pie-chart
Since, 100% area of pie-chart corresponds to ${360}^0$
Therefore, 65% will subtend $=\frac{65}{100}\times {360}^0=18\times 13={234}^0$
