A) Wheat, Barley and Jowar
B) Rice, Wheat and Jowar
C) Rice, Wheat and Barley
D) Bajra, Maize and Rice
Correct Answer: C
Solution :
The total of the central angles corresponding to the three crops which cover 50% of the total area, should be 180°. Now, the total of the central angles for the given combinations are: (A) Wheat, Barley and Jowar \[=({{72}^{o}}+{{36}^{o}}+{{18}^{o}})={{126}^{o}}\] (B) Rice, Wheat and Jowar \[=({{72}^{o}}+{{72}^{o}}+{{18}^{o}})={{162}^{o}}\] (C) Rice, Wheat and Barley \[=({{72}^{o}}+{{72}^{o}}+{{36}^{o}})={{180}^{o}}\] (D) Bajra, Maize and Barley \[=({{18}^{o}}+{{45}^{o}}+{{72}^{o}})={{135}^{o}}\] Clearly (C), is the required combination.You need to login to perform this action.
