Directions (Q91–95): Food X contains 6 units of vitamin D and 7 units of vitamin E per gram and costs ₹12 per gram. Food Y contains 8 units of vitamin D and 12 units of vitamin E per gram and costs ₹20 per gram. The daily minimum requirements of vitamins D and E are 100 units and 120 units. Let x and y be the grams of food X and Y.

Show answer & explanation
Correct answer: D. 6 x+8 y >= 100,7 x+12 y >=120, x, y >= 0
Explanation
Vitamin D: 6x + 8y ≥ 100. Vitamin E: 7x + 12y ≥ 120. Plus x, y ≥ 0.
