Hey Mate , Here is your answer :- Let total capacity of tank = 6 units ∴ Efficiency of A/hr.=6 / 6= 1/ unit Half tank capacity=6 / 2 =3units It will be filled in = 3 hrs According to question, 3 more taps of capacity (1 unit/ hr) are opened with first tap Total capacity of 4 taps = 4 units/hrs They will fill the tank in =Remaining capacity / efficiency=3units / 4units/h= 3/4hours Total time =3 3/4hrs = 3 hr. 45 min Hope , this will help you.
