The average weight of 6 students increases by 2 kg when one student weighing 44 kg is replaced by a new student. What is the weight of the new student?
A. 12 kg
B. 46 kg
C. 56 kg✓ Correct Answer
D. 32 kg
💡 Solution & Explanation
If the average rises by 2 kg for 6 students, the total weight rises by 6 × 2 = 12 kg. The only change is the swap, so the new student weighs 12 kg more than the one who left: 44 + 12 = 56 kg.
