Two vessels of equal capacity contains juice and water in the ratio of 5 : 1 and 5 : 7 respectively. The mixture of both the vessels are mixed and transferred into a bigger vessel. What is the ratio of juice and water in the new mixture?
Let capacity of each vessel = L.C.M. (6,12) = 12 units
Quantity of juice in first vessel = $$\frac{5}{(5+1)}\times12=10$$ units
=> Quantity of water in first vessel = $$12-10=2$$ units
Similarly, juice in second vessel = $$5$$ units and water = $$7$$ units
Now, ratio of juice and water in the new mixture = $$\frac{(10+5)}{(2+7)}$$
= $$\frac{15}{9}=\frac{5}{3}$$
=> Ans - (B)
