You are given 4 items as {value, weightþairs in this format {{20,5}, {60, 20}, {25, 10}, {X, 25}}You can assume that the array is sorted based on the value weight ratio. The capacity of knapsack is 53. The item no. 4 (whose weightis 25 ) is taken fractionally to fill upto the knapsack capacity. That fraction is represented in format. What is the lowest possible value of a? For the question above, assume the total value stored in the knapsack is 145 after you have filled upto the knapsack capacity. What is the value of X(in other words, the valueof the item no. 4) ? Give your answer to at least two decimal places.
