Calculation of Cherry Sales After Lunch

To calculate the amount of cherries sold after lunch, we need to first determine the total weight of cherries and then calculate the amount sold after lunch.

Given: - Total weight of cherries brought to the store: 150 kg - Percentage of cherries sold before lunch: 20% - Percentage of cherries sold after lunch: 2/3 (or 66.67%)

Calculation Steps:

1. Calculate the weight of cherries sold before lunch: - Percentage of cherries sold before lunch: 20% - Weight of cherries sold before lunch = 20% of 150 kg - Weight of cherries sold before lunch = 0.20 * 150 kg

2. Calculate the weight of cherries sold after lunch: - Percentage of cherries sold after lunch: 66.67% - Weight of cherries sold after lunch = 66.67% of the remaining cherries - Remaining cherries = Total weight of cherries - Weight of cherries sold before lunch - Weight of cherries sold after lunch = 66.67% of (Total weight of cherries - Weight of cherries sold before lunch)

Let's calculate the values:

1. Weight of cherries sold before lunch: - Weight of cherries sold before lunch = 0.20 * 150 kg - Weight of cherries sold before lunch = 30 kg

2. Weight of cherries sold after lunch: - Remaining cherries = 150 kg - 30 kg - Remaining cherries = 120 kg - Weight of cherries sold after lunch = 66.67% of 120 kg - Weight of cherries sold after lunch = 0.6667 * 120 kg

Therefore, the weight of cherries sold after lunch is approximately 80 kg.
