Given data:
Average weight(Male) = 170 pounds
Average weight(Female) = 120 pounds
Let the number of females be F, and the number of males beM
1. The group contains twice as many females as males.
If the number of females is twice the number of males F:M = 2:1
Using this ratio, we can determine the average weight of the group
Average weight = 170*2 + 120/3 = 460/3(Sufficient)
2. The group contains 15 more females than males.
= M + 15
Based on the number of M, F will change and give us different
