370

Step-by-step explanation:

Let the code be: abc

Clues:

⇒ Starting with clue 4 and discarding 1,5 and 6

⇒ Clue 2 and 5 ⇒ discarding 9 since contradicting statements, it can't be in the second place as it is wrong according to other statement

⇒ Clue 5 and 3 ⇒ 3 is left as correct digit and goes to first place to replace a.

⇒ Clue 1 and 2 ⇒ discarding 4 as it can't be right and wrong same time

⇒ Clue 2 ⇒ since other 2 digits are discarded, 0 left as correct digit and it goes to third place to replace c.
