Answer: (4)
Solution: (4)
Amount with $A=$ Rs. $x$
$\therefore$ Amount with $C=$ Rs. $\frac{3 x}{4}$
$\therefore$ Amount with $B$ $=$ Rs. $\left(\frac{3 x}{4}-50\right)$
$\therefore x+\frac{3 x}{4}-50+\frac{3 x}{4}=250$
$\Rightarrow x+\frac{3 x}{2}=250+50=300$
$\Rightarrow \frac{2 x+3 x}{2}=300$
$\Rightarrow \frac{5 x}{2}=300$
$\Rightarrow x=\frac{300 \times 2}{5}=$ Rs. 120
