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 :

Let us assume the required number be n.
As per given question,

⇒ n ×	5	− n ×	5	= 25
	4		14

⇒ 5n		1	−	1		= 25
		4		14

⇒ 5n		7 − 2		= 25 ⇒ 5n ×	5	= 25
		28			28

⇒ n =	25 × 28	= 28
	5 × 5
