Answer: B. 240
Step-by-step explanation:
Let the number of pages read by Rafael be 'x'.
Then, The number of pages read by Denise =[tex]\frac{3}{4}x[/tex]
The numb er of pages read by Philippe =[tex]\frac{1}{2}x[/tex]
According to the question :-
[tex]x+\frac{3}{4}x+\frac{1}{2}x=540\\\\\Rightarrow \frac{4x+3x+2x}{4}=540\\\\\Rightarrow \frac{9x}{4}=540\\\\\Rightarrow x=\frac{540\times4}{9}\\\\\Rightarrow x=240[/tex]
The number of pages read by Rafael =240
