Show answer & explanation

Correct answer: C

Explanation:

We must use both given pieces of information: the third girl's weight is 75% of the average, and the total weight of the five girls is 150 kg.

  1. Find the average weight: total weight 150 kg ÷ 5 girls = 30 kg.

  2. Find the third girl's weight: 75% of the average = 0.75 × 30 kg = 22.5 kg.

Answer: The third girl weighs 22.5 kg.
