Question

500grams of salt water in a bucket.8% of that salt water is salt. To decrease the percentage of salt to 5%, how much distilled water should be added to the bucket?

Answer 1

Answer:

Distilled water equivalent to the weight of 300gms should be added.

Step-by-step explanation:

Given 500gms of water is in the bucket of which 8percent is salt water.

(8/100)*500=40gms of salt water.

Now this 40 gms must be made 5percent by adding 'x' gms of distilled water.

Now,

(x/100)*5=40. [5percent of the total water is salt water]

=>x=800.

i.e., If the total quantity of water becomes 800gms then the salt water will be 5percent of it.

Therefore the distilled water added can be found be subtracting the initial amount of water from 800

i.e.,800-500=300.

Therefore 300gms of distilled water is added to make the salt water content 5percent.
