Given that fat provides 9 kcal per gram and protein provides 4 kcal per gram, Food A provides (10 grams of fat * 9 kcal/gram) + (5 grams of protein * 4 kcal/gram) = 90 + 20 = 110 kcal. Food B provides (5 grams of fat * 9 kcal/gram) + (10 grams of protein * 4 kcal/gram) = 45 + 40 = 85 kcal. Therefore, Food A provides 110/85 * 100 = 129% of the kcalories provided by Food B.
