First, You should go to the food value from you source which are for 3 types of food: Carbohydrate 4 Cal/g ---- Protein 4 Cal/g ------- Fat 9 Cal/g.

Note * These are constant and should be available to answer the question "

Sol: Calculate the Calorie from each one the Carbohydrate, protein and Fat.

Carbohydrate in this question are 6 gram. So,

Cal from Carbohydrate = 6 g x 4 Cal/g (given) from above / 1g ( constant) = 24 Cal.

Cal from Fat = 16 x 9 / 1 = 144 Cal.

Cal from Protein = 7 x 4 /1 = 28 Cal.

Now just add the Total Cal which is Total Cal = 28+144+24 = 196 Cal.
