Correct Answer: D
Solution :
Ratio of water and milk are 2 : 7 Total mixture is 729 ml \[{{A}_{1}}:{{A}_{2}}=2:5.\]Quantity of milk \[{{I}_{1}}=\frac{PTR}{100}\] Quantity of water \[{{I}_{2}}=\frac{PTR}{100}\] Now, \[\frac{567}{162+x}=\frac{7}{3}\] \[=\frac{1200\times 3\times 18}{100}\] \[=Rs.432\]\[=Rs.648\]\[{{I}_{1}}:{{I}_{2}}=432:648=2:3.\]
