Means weight in pounds

Question

the total weight of 5 women and 3 men is 1100 pounds. if the mean weight of the women is 115 pounds, what is the mean weight, in pounds, of the men ?

Answer 1

Since we know that there are 5 women, we can multiply their mean weight by 5 to calculate for the total weight of the women: 5 * 115 = 575

We know that the total weight of both men and women is 1100, therefore we subtract 575 from 1100 to get 525, which is the weight of the men.

Since there are 3 men, we divide 525 by 3 to get the mean weight of the men, which would be 175.
