Question

2. A milkman mixes water and milk in the ratio of 3:7
while the milk sold by other milkman has water and
milk in the ratio 4:11. Who is selling a better quality
milk in terms of greater milk content in it?​

Answer 1

Step-by-step explanation:

Milkman 1:

$= \frac{7}{10}$

Milkman 2:

$= \frac{11}{15}$

LCM:

Milkman 1:

$\frac{7 \times 3}{10\times 3} = \frac{21}{30}$

Milkman 2:

$\frac{11 \times 2}{15 \times 2} = \frac{22}{30}$

Therefore, milkman 2 has better quality milk.
