Question

The angle subtended by blue portion at the center of following pie-chart is _____(in degrees).

• A. 234

Answer 1

The correct option is A 234
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 $=\frac{65}{100}\times {360}^0=18\times 13={234}^0$
