وَفِي أَرْبَعِينَ: مُسِنٌّ أَوْ مُسِنَّةٌ.
Translation: And at forty cattle, one musinn or musinnah is due.
At 40 cattle, the due animal is a musinn (male) or musinnah (female), each having completed two years and entered the third.
Thus, 39 cattle call for a tabi‘ or tabi‘ah, while 40 shift the requirement to an older age class. This is a transition between legal brackets, not simply a proportional monetary increase.
