Question

a drum full of rice weighs 40 1/6 kg if the empty drum weighs 13 3/4 find the weight of rice in the drum

Answer 1

$$\begin{gathered} \mathrm{Weight}\mathrm{of}\mathrm{drum}\mathrm{filled}\mathrm{with}\mathrm{rice}=40\frac{1}{6}\mathrm{kg}=\frac{241}{6}\mathrm{kg} \\ \mathrm{Weight}\mathrm{of}\mathrm{empty}\mathrm{drum}=13\frac{3}{4}\mathrm{kg}=\frac{55}{4}\mathrm{kg} \\ \mathrm{Weight}\mathrm{of}\mathrm{rice}=\frac{241}{6}-\frac{55}{4}=\frac{482-165}{12}=\frac{317}{12}=26\frac{5}{12}\mathrm{kg} \end{gathered}$$
