Answer:
If number begin with 1
The remaining digit to be arranged will be 0,2,2,2,4,4
Here three 2s and two 4s
Since digit are repeating hence we use this formula=
p
1
!p
2
!p
3
!
n!
Number of remaining digit=6
Thus, n=6
Since three 2s and two 4s
and p
1
=3, p
2
=2
The number of numbers beginning with 1=
p
1
!p
2
!
n!
=
3!2!
6!
=
3!×2×1
6×5×4×3!
=60
