Below are the steps: Find the ratio value/weight for each item and sort the item on the basis of … WebGreedy approach: In Greedy approach, we calculate the ratio of profit/weight, and accordingly, we will select the item. The item with the highest ratio would be selected first. There are basically three approaches to solve the problem: The first approach is to select the item based on the maximum profit.
