Question
In a mixture of milk and water the proportion of water by weight was 25%. If in the 60 gm mixture, 15 gm water is added, what would be the percentage of water? (weight in gm).a.50%b.40%c.33.33%d.63%
Solution
Sure, let's solve this step by step:
Step 1: In the original 60 gm mixture, the amount of water was 25%. So, the weight of the water was 25/100 * 60 = 15 gm.
Step 2: Now, 15 gm of water is added to the mixture. So, the total weight of water in the mixture becomes 15 gm (original) + 15 gm (added) = 30 gm.
Step 3: The total weight of the mixture after adding water becomes 60 gm (original) + 15 gm (added) = 75 gm.
Step 4: Now, we need to find the percentage of water in the mixture. The formula to calculate the percentage is (part/whole) * 100. So, the percentage of water in the mixture is (30/75) * 100 = 40%.
So, the answer is b. 40%.
