Initial ratio = 5 ∶ x After adding 1 liter of water to the 4 liters of blend, the final quantity of the blend becomes 5 Liters Final Ratio = 1 ∶ 1 ⇒ Value of 2 = 5 Liters ⇒ Quantity of juice = Quantity of water in the blend = 2.5 Liters Since the Quantity of juice is same, ⇒ Quantity of juice in initial mixture = 2.5 Liters ⇒ Quantity of water in initial mixture = 1.5 Liter ⇒ Initial total quantity = 4 Liters 4 Liters in mixed in the ratio = 2.5 ∶ 1.5 = 5 ∶ 3 ∴ Value of x = 3
