(A) Total weight of $24$ students $= 24 	imes 35 = 840\, kg$.The new average weight after including the teacher $= 35\, kg + 400\, g = 35\, kg + 0.4\, kg = 35.4\, kg$.The total number of people including the teacher $= 24 + 1 = 25$.Total weight of $25$ people $= 25 	imes 35.4 = 885\, kg$.Weight of the teacher $= (	ext{Total weight of } 25 	ext{ people}) - (	ext{Total weight of } 24 	ext{ students})$.Weight of the teacher $= 885 - 840 = 45\, kg$.

The average weight of $24$ students is $35\, kg$. If the weight of the teacher is added, the average increases by $400\, g$. What is the weight of the teacher in $kg$?
