Answer»

LET the four digit number be 1000x + 100y + 10Z + n

Statement I

⇒ n = z/3

⇒ 3n = z

Statement II

⇒ n = y/5

⇒ 5n = y

&

⇒ n = x/2

⇒ 2n = x

Statement III

SUM of all the digits is 11.

Now, putting all values

⇒ 3n + 5n + 2n + n = 11

⇒ 11n = 11

⇒ n = 1

Hence, the number is 2531.

∴ All the statements together are REQUIRED to answer the question.
