Question

The capacity of a water tank is 2540 litres. If 3/10 of the water leaked through a hole, then find the quantity of the water remaining in the tank?

Answer 1

$$\begin{gathered} \mathrm{Capacity}\mathrm{of}\mathrm{water}\mathrm{tank}=2550\mathrm{Liters} \\ \mathrm{water}\mathrm{leaked}=\frac{3}{10}\times 2550\mathrm{Liters}=765\mathrm{Liters} \\ \mathrm{Remaining}\mathrm{water}=2550\mathrm{Liters}-765\mathrm{Liters} \\ =1785\mathrm{Liters} \end{gathered}$$
