Six persons - A, B, C, D, E and F have different numbers of chocolates.
Atleast three people have less chocolates than B.
|  | Case 1 |  | Case 2 |  | Case 3 |  | 
| Sr. no | People | No. of chocolates in descending order | People | No. of chocolates in descending order | People | No. of chocolates in descending order | 
| 1 |  |  |  |  | B |  | 
| 2 |  |  | B |  |  |  | 
| 3 | B |  |  |  |  |  | 
| 4 |  |  |  |  |  |  | 
| 5 |  |  |  |  |  |  | 
| 6 |  |  |  |  |  |  | 
Only three persons have different numbers of chocolates between B and E, who have more chocolates than F. Thus, case 1 and case 2 are invalid.
F has 200 chocolates.
|  | Case 3 |  | 
| Sr. no | People | No. of chocolates in descending order | 
| 1 | B |  | 
| 2 |  |  | 
| 3 |  |  | 
| 4 |  |  | 
| 5 | E |  | 
| 6 | F | 200 | 
A has more chocolates than C and less than D. D has 700 chocolates.
| Sr. no | People | No. of chocolates in descending order | 
| 1 | B |  | 
| 2 | D | 700 | 
| 3 | A |  | 
| 4 | C |  | 
| 5 | E |  | 
| 6 | F | 200 | 
One of the persons has 900 chocolates.
Therefore, the final arrangement is:
| Sr. no | People | No. of chocolates in descending order | 
| 1 | B | 900 | 
| 2 | D | 700 | 
| 3 | A |  | 
| 4 | C |  | 
| 5 | E |  | 
| 6 | F | 200 | 
C can have chocolates between 200 to 700. So, we cannot determine the numbers of chocolates with C.
