A. 19 : 4
B. 7 : 3
C. 61 : 29
D. 41 : 18
Answer: Option C
Solution(By Examveda Team)
$$\eqalign{ & {\text{Milk in the mixture}} \cr & = \left( {\frac{3}{5} + \frac{7}{{10}} + \frac{{11}}{{15}}} \right){\text{units}} \cr & = \frac{{61}}{{30}}{\text{units}}{\text{.}} \cr & {\text{Water in the mixture}} \cr & = \left( {\frac{2}{5} + \frac{3}{{10}} + \frac{4}{{15}}} \right){\text{units}} \cr & = \frac{{29}}{{30}}{\text{units}}{\text{.}} \cr & \therefore {\text{Required ratio}} \cr & = \frac{{61}}{{30}}:\frac{{29}}{{30}} \cr & = 61:29 \cr} $$Related Questions on Ratio
