Question

In mid-day meal scheme $\frac{3}{10}$ litre of milk is given to each student of a primary school. If 30 litres of milk is distributed every day in the school, how many students are there in the school?

Answer 1

Number of students in the school = $\frac{\mathrm{Total}\mathrm{amount}\mathrm{of}\mathrm{milk}\mathrm{distributed}\mathrm{per}\mathrm{day}}{\mathrm{Amount}\mathrm{of}\mathrm{milk}\mathrm{given}\mathrm{to}\mathrm{one}\mathrm{student}}$
$$\begin{gathered} =30÷\frac{3}{10} \\ =\cancel{{30}^{10}}\times \frac{10}{\cancel{3}} \\ =100 \end{gathered}$$
