Question

3 litres of water is mixed with 12 litres of milk in a pot and another pot contains 4 litres of water with 10 litres of milk. What is the ratio of the strengths of milk of the two mixtures?​

Answer 1

Answer:

Volume of pure milk in 4- Litres of 7:1 milk-water mixture= 7/8 x4= 28/8 Litres

Volume of pure milk in 6- Litres of 9:7 milk-water mixture= 6 x 9/16= 27/8- Litres.

So volume of pure milk, in the total 10- Litres of milk-water mixture =28/8+27/8 = (55)/8.

So Volume of water in the final 10- Litre milk-water mixture= (10–55/8) = 25/8.

Therefore the ratio of the milk-water mixture in the final resultant mixture =55/8 : 25/8 = 55 : 25

= 11 : 5

Answer 2

Answer:

in case I ,

milk : water = 12 : 3 = 3 : 1

in case ll ,

milk : water = 10 : 4 = 5 : 2
