Question

Four vessels of equal size are filled with mixtures of milk and water. The strength of milk in the four vessels is 80%, 75%, 60% and 50% respectively. If all four mixtures are mixed, what is the ratio of water to milk in the resultant mixture?

• A. 27 : 53
• B. 13 : 27
• C. 29 : 51
• D. 3 : 5

Answer 1

Answer:

A. 27 : 53

milk in water $80$

so the ratio of milk and water is $80:20,75:25,60:40,50:50$

mix all together we get the ratio of water to milk

$\frac{20+25+40+50}{80+75+60+50}$

$\frac{135}{265}$

$\frac{27}{53}=27:53$
