• A. Gain of $750$ calories
• B. Loss of $750$ calories
• C. Gain of $150$ calories
• D. Loss of $150$ calories

Answer 1

The correct option is C Gain of $150$ calories

In the morning, Markus burnt $300$ calories, this means there is a loss of $300$ calories from the body of Markus.

After taking breakfast, Markus gained $450$ calories.

As $450>300$, there would be a gain of calories by Markus after taking breakfast.

Calories gained by Markus after taking breakfast
$=(-300+450)$ calories
$=150$ calories

$\therefore$ On that particular day, Markus finally gained $150$ calories, i.e., option (c.) is the correct one.
