In a mixture of milk and water the proportion of water by weight was 75%. If in 60 gm of mixture 15 gm water was added, what would be the percentage of water? (Weight in gm)

Options
(1) 75%
(2) 88%
(3) 90%
(4) 100%

• Ans: 80%
  
  Water in 60 gm mixture=60*75/100=45 gm. and Milk=15 gm.
  After adding 15 gm. of water in mixture,total water=45+15=60 gm and weight of a mixture=60+15=75 gm.
  So % of water=100*60/75=80

• Answer 80%
  Explanation:
  Amount of water in 60 g = 60 * 75/100 = 45 g
  After adding 15 g of water in mixture = 45 + 15 = 60 g
  Percentage of water in mixture = 60/(60 + 15) *100 = 80%
