$A$ mixture of benzene and toluene forms

$5$ moles of liquid $X$ and $10$ moles of liquid $Y$ make a solution having a vapour pressure of $70 \ torr$. The vapour pressures of pure $X$ and $Y$ are $63 \ torr$ and $78 \ torr$ respectively. Which of the following is true regarding the described solution?

Two liquids $A$ and $B$ form an ideal solution. What will be the vapor pressure of a solution containing a mole ratio of $A$ and $B$ as $3:1$ in $torr$? $(Given: P_A^o = 24 \ torr, P_B^o = 40 \ torr)$

Which of the following is not correct?

Assertion $A$: For an ideal solution formed by mixing liquids $P$ and $Q$, $\Delta_{mix} H = 0$ and $\Delta_{mix} V = 0$.
Reason $R$: No interactions occur between $P$ and $Q$.
In the light of the above statements, choose the most appropriate answer from the options given below:

Which of the following solutions behaves nearly as an ideal solution?
