Đáp án đúng là: B

$\{\begin{array}{l}\text{T}\text{r}\text{i}\text{s}\text{t}\text{e}\text{a}\text{r}\text{i}\text{n}\text{:}n{}_{\text{T}\text{r}\text{i}\text{s}\text{t}\text{e}\text{a}\text{r}\text{i}\text{n}}=\frac{100000.44,5\mathrm{\%}}{890}=50 \text{m}\text{o}\text{l}\\ \text{T}\text{r}\text{i}\text{p}\text{a}\text{l}\text{m}\text{i}\text{t}\text{i}\text{n}\text{:}n{}_{\text{T}\text{r}\text{i}\text{p}\text{a}\text{l}\text{m}\text{i}\text{t}\text{i}\text{n}}=\frac{100000.24,18\mathrm{\%}}{806}=30 \text{m}\text{o}\text{l}\\ \text{T}\text{r}\text{i}\text{o}\text{l}\text{e}\text{i}\text{n}\text{:}n{}_{\text{T}\text{r}\text{i}\text{o}\text{l}\text{e}\text{i}\text{n}}=\frac{100000.26,52\mathrm{\%}}{884}=30 \text{m}\text{o}\text{l}\end{array}\Rightarrow \{\begin{array}{l}m{}_{\text{s}\text{o}\text{d}\text{i}\text{u}\text{m}\text{s}\text{t}\text{e}\text{a}\text{r}\text{a}\text{t}\text{e}}=50.3.306.80\mathrm{\%}=36720 \text{g}\\ m{}_{\text{s}\text{o}\text{d}\text{i}\text{u}\text{m}\text{p}\text{a}\text{l}\text{m}\text{i}\text{t}\text{a}\text{t}\text{e}}=30.3.278.80\mathrm{\%}=20016 \text{g}\\ m{}_{\text{s}\text{o}\text{d}\text{i}\text{u}\text{m}\text{o}\text{l}\text{e}\text{a}\text{t}\text{e}}=30.3.304.80\mathrm{\%}=21888 \text{g}\end{array}$

⇒ m _{xà phòng} $=(36720+20016+21888).\frac{100}{72}=109200 \text{g}$.

⇒ Số bánh xà phòng $=\frac{109200}{90}\approx 1213$ bánh.
