Question

The diet of a $20$ yrs old girl include $100$ ml of water, $100$ g inulin and $50$ g cellulose. Assuming complete digestion of the diet, how many calories she is likely to get?

• A. $150$
• B. $400$
• C. $600$
• D. $0$

Answer 1

The correct option is A $150$

Water is meant to give no calories on digestion.

1g Inulin (a type of polysaccharide) gives 1.5 calories on complete digestion.

Cellulose cannot be digested by humans due to the absence of digesting enzymes for cellulose.

So, water will give = 100 mL x 0 calories = 0 calories.

Inulin will give = 100 x 1.5 calories = 150 calories.

50 g cellulose will give = 50 x 0 calories = 0 calories.

Thus, adding all the individual data we get the girl will get = 0+150+0 calories

150 calories.
