					 A candidate in an examination was asked to find 5/14 of a certain number. By mistake he found 5/14 of it. Thus, his answer was 25 more than the correct answer. The number was :
- 
                        - 28
- 56
- 84
- 140
 
Correct Option: A
Let us assume the required number be n.
As per given question,
| ⇒ n × | − n × | =  25 | ||
| 4 | 14 | 
| ⇒ 5n |  | − |  | = 25 | ||
| 4 | 14 | 
| ⇒ 5n |  |  | = 25 ⇒ 5n × | = 25 | ||
| 28 | 28 | 
| ⇒ n = | = 28 | |
| 5 × 5 |
