Correct option (4) 2404
Explanation:
The number of all five digit numbers that can be formed with 0, 1, 3, 5,7 = 4.54
(∴ 0 cannot occur in the 10000th place)
= 2500
The number of numbers without any repetition
= 4 × 4 × 3 × 2 × 1 = 96
∴ the number of five digit numbers with at least one digit repeated
= 2500 − 96 = 2404
