Dear Student, Amount of dettol water used in first operation = 23Second operation = 23×23= 49third operation = 49×23= 827fourth operation = 827×23= 1681Amount of water after fourth operation = 1- 1681= 6581therefore, required ratio =1681: 6581= 16:65Regards

A bottte is full of dettol. One-third of it is taken out and then an equal amount of water is poured into the bottle to fill it, This operation is done four times. Find the final ratio of dettol and water in the bottle.
