I think that the answer should be 'A' (instead of 'C') because total calories consumed are immaterial when calculating the ratio.
is a question ambiguous? The question is asking if the guy fits the ratio. (1) Says to us that he definitely does. I don't see any restrictions strictly showing how many calories should be derived. Thus I also considered calories info irrelevant.

To reiterate what Bunuel mentioned in his original solution, the key is that statement 1 only gives us information on what he ate for 1 meal that day. True, that meal followed the ratio, but statement 1 is not sufficient because the original question is asking whether the person followed the ratio THAT DAY, not just for 1 meal. We do not have information on what that person ate for other meals of the day.

Statement 2 is not sufficient either because we don't know the breakdown of the 1500 calories and cannot check the ratio.

However, when we combine both statements, they basically tells us that the person only ate 1 meal that day - the meal mentioned in statement 1. This is why C is the answer (1+2 are sufficient).

Hope this helps.

A certain diet program calls for eating daily calories from carbohydrates, proteins, and fats in the ratio of 40:30:30 respectively. On a certain day, did Bill follow this diet program? (1 gram of fat contains 9 calories, 1 gram of protein contains 4 calories, and 1 gram of carbohydrates contains 4 calories)

(1) One of the meals Bill ate contained 80 grams of carbohydrates, 60 grams of protein, and 60 grams of fat --> we have info only about one meal Bill ate. Not sufficient.
Though from this statement we can find out how much calories did Bill get from this meal:
80 grams of carbohydrates = 4*80 = 320 calories;
60 grams of protein = 4*60 = 240 calories;
60 grams of fat= 9*60 = 540 calories.

(2) Bill ate 1500 calories during the day --> no info about the ratio. Not sufficient.

(1)+(2) To follow his diet Bill should have had 30%*1,500=450 calories from fat but (1) tells that Bill already exceeded this limit in one particular meal, so clearly he did not follow his diet program. Sufficient.

How do consider 1500 calories being comprised only of fats, protein and carbohydrates?The main statement just mentions that the ration of these three nutrients.
