Answer 2

33 litre of water must be added in order to fill the tank to the brim

Step-by-step explanation:

Total capacity of the tank = 45 ltr

Water filled in the tank = $\frac{4}{9}\times45$

                                       = 20 ltr

Water removed from the tank = $\frac{2}{5}\times 20$

                                                  = 8 ltr

Remaining water in the tank = 20 ltr - 8 ltr

                                               = 12 ltr

Capacity of water added to fill the tank

                  = Total capacity of water - remaining water in the tank

                  = 45 ltr - 12 ltr

                  = 33 ltr

Hence 33 litre of water must be added in order to fill the tank to the brim.
