So, you could use 50 0,1 or 2 times.
If you use 50 2 times, you can only use 1s to get to 107.
That is 1 way to do it.
(Using 2 50s, 0 10s and 7 1s.)
If you use 50 once, you could use 10 {0, 1, 2, 3, 4, 5} = total 6 times. Remaining would be filled by 1s
That is 6 different ways to do it.
If you use 50 0 times, you could use 10 {0, 1,2 ,3 ,4 ,5 ,6 ,7 ,8 , 9, 10} = 11 times. Remaining would be filled by 1s.
That is 11 different ways to do it.
Since you would go either one of these routes,
Total no. of ways = 1 + 6 + 11 = 18 ways.
Ans D.
