Question

68 kg of mixture contains milk and water in the ratio 27 is to 7 how much more water is to be added to this mixture to get a new mixture containing milk and water in the ratio 3 is to 1 ​

Answer 1

Answer:

4 litre

Step-by-step explanation:

68 litre of mixture contains milk and water in the ratio 27 : 7

i.e 54 litre milk and 14 litre water

X litre of water is added to get new mixture in ratio 3:1

$\frac{milk}{water} = \frac{54}{14 + x} = \frac{3}{1}$

$54 = 42 + 3x$

X = 4 litre

(or)

54:14

To get new mixture we only add water. So milk is 54 in final solution also.

$\frac{ 54}{3} \times 1 = 18 \: litre$

Hence water in final solution = 18 litre

water added = 18 - 14 = 4 litre
