A container of 64 ltr was full of milk. 16 ltr mik was drawn off and replace by water and this process is repeated 2 timemore find the quantity of water in the mixutre now..

Question

mixture and alligation..

Answer 1

64-16=48L of milk. When topped up with water the amount of milk is now 48/64=3/4 (75%). This leaves 1/4 (25%) water.

64-16=48L of solution. 3/4 of this solution was milk and 1/4 water. So the amount of milk drawn off this time is 3/4 of 16=12L. So, in all 16+12=28L of milk have been drawn off, leaving 64-28=36L. The concentration of milk is now 36/64=9/16. Water must therefore be 7/16 of the solution (28L).

64-16=48L of solution. 9/16 of the 16L=9L milk. In all, 16+12+9=37L have been drawn off, leaving 64-37=27L of milk, a concentration of 27/64. Water content is now 37/64 (57.8125%) or 37L.

 

Answer 2

Answer: water = 37 Liters.

Times	Total	Milk	Water	Details
0	64	64	0
1	64	64-16=  48	16
2	64	48-12= 36	16-4+16 = 28	64 ltr milk is combined of milk and water as 4:1 portion. So, if 16 ltr milk water is 4ltr, and milk is 12 lit
3	27+37= 64	36- (16/64*36) = 36-9 = 27	28-(16/64*28) = 28 – 7 = 21+16 = 37
