Question 70
The identical jars are fully filled with acid solutions, the ratio of volume of acid to the volume of water being 1 : 1 in one jar and 2 : 1.in the otherjar. If the entire contents of two jars are mixed together, the ratio of volume of water to the volume of acid in the mixture is
Solution
Since, the jars are identical (have same capacity). Let quantity of each jar be L.C.M. (2,3) = 6 units
=> Acid in jar one = 3 units and acid of water in jar 1 = 3 untis
Similarly, Acid in jar two = 4 units and water in jar two = 2 units
When mixed together, ratio of water to acid = $$(3+2):(3+4)=5:7$$
=> Ans - (A)
