What is the central angle made by students of Goa and M.P?
» Explain it
B
We know that
 
⇒ 100% = 360°
 
∴ 1% = 3.6°
 
Now, Total percentage of students from Goa and M.P. = (12% + 13%) = 25%
 
Thus, the central angle made by these students = 25% × 3.6° = 90°
 
Hence, the correct answer is option B.
