A) 10

B) 15

C) 20

D) 30

E) 60


My approach:

pick 3 digits from 5 digits ---> 5 C 3 = 10

and arranging 3 digits in 3! ways = 6

so total = 6*10 = 60

let's denote each digit of an integer with 1,2,3

1 can be filled in 5 ways
2 in 4
3 in 3

so distinct numbers= 5*4*3=60

p.s. question should mention 5 distinct digits doesn't have 0 in it. else the answer should change to 4*4*3=48, since 023 will be a 2 digit number and not 3 so 1 can be filled in only 4 ways.
