Since, $$\frac{3}{10}$$ of the bucket took 6 minutes to fill.
Therefore, total time to fill the bucket is $$\frac{1}{\frac{3}{10}}\cdot\ 6\ =\ \frac{10}{3}\ \cdot\ 6\ =\ 20$$ minutes.
So remaining time to fill the bucket = $$20\ -\ 6\ =\ 14$$
Therefore, total time to fill the bucket is $$\frac{1}{\frac{3}{10}}\cdot\ 6\ =\ \frac{10}{3}\ \cdot\ 6\ =\ 20$$ minutes.
So remaining time to fill the bucket = $$20\ -\ 6\ =\ 14$$
