The ratios of milk to water in the mixtures of four containers are 5 : 3, 2 : 1, 3 : 2 and 7 : 4 respectively. In which container is the quantity of milk relative to water the least?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Third
Milk relative to water is the value of the fraction milk ÷ water, so the four ratios are compared as fractions.
First: \(\displaystyle \frac{5}{3}=1.67\)
Second: \(\displaystyle \frac{2}{1}=2\)
Third: \(\displaystyle \frac{3}{2}=1.5\)
Fourth: \(\displaystyle \frac{7}{4}=1.75\)
The smallest value is 1.5, so the milk is least, relative to water, in the third container.
