Question

in a mixture of a milk and water, The proportion of water by weight is 75 % . If in the 60g mixture, 15 g of water is added, what would be the percentage of water?

​

Answer 1

Step-by-step explanation:

80%

of water in mixture, total water = 45 + 15 = 60 gm and weight of a mixture = 60 + 15 = 75 gm. So % of water = 100 x 60/75 = 80%

Answer 2

Answer:

80%

Step-by-step explanation:

Water in 60 gm mixture=60×10075=45 gm

 and Milk =60−45=15 gm.

After adding 15 gm. of water in mixture, total water =45+15=60gm and weight of a mixture =60+15=75 gm.So % of water =100×7560=80%
