Correct Answer - C
`(c )` The sum of digits must be divisible by `9`
The pair of missing numbers must be `(1,2)` or `(0,3)`
Case I : `(1,2)`
`implies` when `1` is first digit the remaining digits `(1,2,0,0,5)` can be arranged in `60` days, when `5` or `2` is first digit then in `30` ways each
Case II : `(0,3)` will have `3xx20=60` ways
So total number of ways `=60+2xx30+3xx20=180`
