The correct answer is (C): \(50\)
Let the cost price and marked price of each toy be \(c\) and \(m\) respectively.
Overall selling price = \(8(0.8m)+4\bigg(\frac{3}{4}×0.8m\bigg)\)i.e. \(8.8\) m.
Given, \(110\% \) of \(12\) \(c\) = \(8.8\) m
\(⇒ c=\frac{2m}{3}\)
∴ Overall \(CP\) = \(12×\frac{2m}{3}\) i.e. \(8\) m
Required profit percentage = \(\frac{12m-8m}{8m}×100 = 50\%\)
