Problem Analysis

We need to determine the amount of apples that are left after a certain amount has been delivered to a store. The store initially received 540 kg of apples, and then 2/5 of the remaining apples were delivered before lunch, and 3/4 of the remaining apples were delivered after lunch. We need to calculate the remaining amount of apples.

Calculation

To calculate the remaining amount of apples, we need to subtract the amount of apples delivered before lunch and after lunch from the initial amount of apples.

Let's break down the calculation step by step:

1. Initial amount of apples: 540 kg. 2. Amount of apples delivered before lunch: 2/5 * (initial amount of apples - amount of apples delivered before lunch). 3. Amount of apples delivered after lunch: 3/4 * (initial amount of apples - amount of apples delivered before lunch - amount of apples delivered after lunch). 4. Remaining amount of apples: initial amount of apples - amount of apples delivered before lunch - amount of apples delivered after lunch.

Let's calculate the remaining amount of apples using the given information.

Calculation Steps

1. Initial amount of apples: 540 kg. 2. Amount of apples delivered before lunch: 2/5 * (540 kg) = 216 kg. 3. Amount of apples delivered after lunch: 3/4 * (540 kg - 216 kg) = 243 kg. 4. Remaining amount of apples: 540 kg - 216 kg - 243 kg = 81 kg.

Answer

The remaining amount of apples is 81 kg.
