The right answer is 202.5 - 292.5 grams of carbohydrates a day.

The man's caloric requirements are around 2500 calories / day. So the subject tries to create a calorie deficit.

1 gram of carbohydrate equals 4 calories.

45% - 65% of the calorie intake (1800kcal) corresponds to 0.810 - 1.170 Kcal. (810 and 1170 calories).

So:

4 calories = => 1 gram of carbohydrates

810 calories = => 810/4 = 202.5 grams of carbohydrates

1170 calories = => 1170/4 = 292.5 grams of carbohydrates.

So, the subject must consume between 202.5 and 292.5 grams of carbohydrates a day.
