    Direction: The pie-chart depicts the results of a survey conducted to identify the favourite juice of some students. How many students like other juices if the total number of students is 360?

    A)  70                         

    B)         80  

    C)  65                         

    D)         60  

    Correct Answer: D

    Solution :

       The angle representing students who like other juices is \[{{360}^{o}}-({{90}^{o}}+{{75}^{o}}+{{135}^{o}})={{60}^{o}}\] Total number of students = 360 \[\therefore \]Required number of students \[=\frac{{{60}^{o}}}{{{360}^{o}}}\times 360=60\]
