Total number of female goats that gave birth = 245-9 = 236.
Number of kids born in total = 357.
We know that none of them have had more than two kids.
So, that means the number of goats that have had two kids = Number of Kids born in total - Total number of female goats that gave birth
= 357 - 236 = 121.
Number of goats that have had one kid only = 236 - 121 = 115
