Question

In a solution of common salt in water, the ratio of salt to
water was 30:70 as per weight If we evaporate 100 grams of water
from one kilogram of this solution, what will be the ratio of the
salt to water by weight?

Given
Salt: Water = 30: 70
In 1 kg of solution,
Salt = 300 g and water = 700 g
After evaporating 100 g of water, remaining water =
700-100=600g
So, salt: water=300:600=1:2
