Show Answer

Correct Answer: (3)

Solution: (3)

Number of bags available in store $R$ in December $=x$ (let)

According to the question,

$ \begin{aligned} & \frac{x}{\frac{800 \times 30}{100}}=\frac{7}{6} \\ & \Rightarrow \frac{x}{240}=\frac{7}{6} \end{aligned} $

$\Rightarrow x=\frac{7}{6} \times 240=280$

Required answer $=280-240$ $=40$
