Answer 2

Answer:

4 numbers can be formed

Step-by-step explanation:

using permutations.

first digit can be occupied with only 2 and 5 so 2p1 ways.

second digit can be occupied in 2p1 ways since one number is already placed in first digit place.

third digit will have only one number so 1 way.

2p1 x 2p1 x 1 = 2 x 2 x 1 = 4
