Answer: Only Option 'A' and 'B' are correct.
Step-by-step explanation:
Since we have given that
Number of calories she consumed at breakfast = 400
Number of calories she consumed at lunch = 350
Let number of calories she consumed at dinner be x
According to question,
She consumes [tex]\frac{2}{3}[/tex] of her daily calories at dinner,
So, it becomes,
[tex]\frac{1}{3}\times Total=400+350\\\\\frac{Total}{3}=750\\\\Total=750\times 3=2250[/tex]
so, Number of calories she consumed at dinner is given by
[tex]\frac{2}{3}\times total =x\\\\\implies x=\frac{2}{3}\times 2250=1500[/tex]
And by option 'B' we get,
[tex]\frac{2}{3}(x + 400 + 350) = x \\\\x+750=\frac{3}{2}\times x=\frac{3x}{2}\\\\750=x-\frac{3x}{2}\\\\750=\frac{3x-2x}{2}\\\\750=\frac{x}{2}\\\\750\times 2=x\\\\1500=x[/tex]
so, only Option 'A' and 'B' are correct.
