Answer:
B.
Step-by-step explanation:
So there are 16 grams initally. Then, the amount of water decreases by 3.5%.
So first we must find 3.5% of 16. 3.5% in decimal form is 0.035, since you divide 3.5 by 100. Then, when you multiply 0.035 by 16, you get 0.56. Since the solution decreased by that percentage, you must subtract 0.56 from 16, which is 15.44.
Then the amount of water decreases by 4.25%. That in decimal form is 0.0425. You multiply it by 15.44, and it comes out to 0.6562. You subtract that from 15.44, not 16, since some of the water has evaporated. So you get 14.7838.
Half of the total members are men. For every on women there is one man.
So if there was a total of 100 people in the library and the ratio of man to women was 1:1 there would be 50 women and 50 men.
