Question

in a mixture of milk and water the proportion of water by weight is 75percent if in the 6o g mixture 15 g water is added what would be the percentage of water​

Answer 1

Answer:

the new mixture contains 80% of water and 20% of milk

Step-by-step explanation:

total= milk+water=60g

in total mixture water=75%

amount of water in mixture= 75% of water *60g

                                              =(75/100)*60

                                              =45g

amount of water in mixture=45g

total =60g (water=45g + milk=15g)

new amount added to mixture of water=15g (in this addition of water only increase in water)

so new mixture contains water=45g+15g=60g

  new mixture contains milk=15g (same as old mixture)

total amount of new mixture = 75g (water =60g+milk=15g )

in the new mixture water percentage =(water/total)*100

                                                                 = (60/75)*100

                                                                 =80%

in the new mixture water =80%

             new mixture milk=20%
