Problem Analysis

We are given that after selling one-third of the candies, the weight of the box decreased by 32%. We need to determine the weight of the empty box, given that the full box weighed 45 kg.

Solution

Let's break down the problem step by step:

1. Calculate the weight of the candies that were sold: - One-third of the candies were sold, so the weight of the sold candies is (1/3) * 45 kg.

2. Calculate the weight of the remaining candies: - The weight of the remaining candies is the weight of the full box minus the weight of the sold candies. - The weight of the remaining candies is 45 kg - (1/3) * 45 kg.

3. Calculate the weight of the empty box: - The weight of the empty box is the weight of the full box minus the weight of the remaining candies. - The weight of the empty box is 45 kg - (45 kg - (1/3) * 45 kg).

Let's calculate the weight of the empty box:

Weight of the sold candies = (1/3) * 45 kg = 15 kg.

Weight of the remaining candies = 45 kg - (1/3) * 45 kg = 30 kg.

Weight of the empty box = 45 kg - 30 kg = 15 kg.

Therefore, the weight of the empty box is 15 kg.

Answer

The weight of the empty box is 15 kg.
