When the teacher joins, average increases by 0.4 kg for 36 people (35 students + 1 teacher). Total weight increase = 36 × 0.4 = 14.4 kg. Teacher's weight = original average + total increase = 24 + 14.4 = 38.4 kg. However, using the standard formula: Teacher = new average × new count - old average × old count = 24.4×36 - 24×35 = 878.4 - 840 = 38.4 kg, which rounds to 38 kg.
