plz give step by step answer​

Answer 1

Answer:

total female

Step-by-step explanation:

3/10 (30%) of the members are women and 3/8 of the members are married men. Let the total numbers of members is 80 (the LCM of 10 and 8). Then there are:

3/10*80 = 24 women;

80 - 24 = 56 men;

3/8*80 = 30 married men;

56 - 30 = 26 unmarried men.

So, only option III is true.
