Answer 1

Answer:

Step-by-step explanation:

Mean weight of 50 students = 52 kg

∴ Total weight of 50 students = 52 × 50 kg = 2600 kg

Mean weight of 30 students among them = 54 kg

∴ Total weight of 30 students = 54 × 30 kg = 1620 kg

∴ Remaining students = 50 – 30 = 20 and total weight of 20 students

= 2600 – 1620 = 980 kg

∴ Mean weight of 20 students = 980/20 = 59 kg
