Answer:
No; 1,000 will cause him to exceed 1,800.
Explanation:
Given,
The consumed calories = 1,600,
Burned calories = 400,
Thus, the remaining calories = 1600 - 400 = 1200
Since, 1,800 calories per day would be like to keep,
Also, 1200 < 1800
Hence, remaining calories is less than the required calories,
And, the calories left to consume for the day = Required calories - remaining calories
= 1800 - 1200
= 600
Therefore, 600 is the viable solution to this problem.
Note : If 1,000 a viable solution to this problem then the required calories will be more than 1800 or exceed 1800.
