Correct Answer: C
Solution :
| Number of students prefer beverages A and C together |
| \[=6800\times \left( \frac{79.2+14.4}{360} \right)=6800\times \frac{93.6}{360}=1768\] |
| Number of students prefer beverages D and F together |
| \[=6800\times \left( \frac{122.4+21.6}{360} \right)=680\times \frac{144}{360}=2720\] |
| \[\therefore \]Required difference \[=2720-1768=952\] |
