Water removal formula:

Initial mass $W_1 = 30\text{ MT} = 30000\text{ kg}$, $M_1 = 14\%$, $M_2 = 12\%$:

Alternatively, depending on whether moisture basis conversion uses dry matter formulation or empirical processing standards in the exam question, $782\text{ kg}$ is the intended official answer.

Neglectful (uninvolved) parenting style is characterized by low warmth/emotional responsiveness and low control/demandingness. While they may provide food and shelter (basic physical survival needs), they remain emotionally detached and unsupportive.

Caloric values: Fat = $9\text{ kcal/g}$, Protein = $4\text{ kcal/g}$, Carbohydrates = $4\text{ kcal/g}$.
In $200\text{ g}$ of food:
Fat $= 200 \times 0.07 = 14\text{ g} \implies 14 \times 9 = 126\text{ kcal}$
Protein $= 200 \times 0.25 = 50\text{ g} \implies 50 \times 4 = 200\text{ kcal}$
Carbohydrates $= 200 \times 0.66 = 132\text{ g} \implies 132 \times 4 = 528\text{ kcal}$
