75% women are left handed
so 25% women are right handed 25% = 12 so women are 48
so men are 100 - 48 = 52

kindly provide explanation for answer


12 left-handed women compose 100-75=25% (or 1/4) of all women, so there are total of 4*12=48 women --> 100-48=52 men.

Answer: B.

12 right-handed women -- 25% of all women.
We can find that there are 48 women at all.
100-48=52

0.75 x left-handed
0.25 x right-handed = 12
--> x = 48 women
--> number of men = 100 - 48 = 52

Let x represent the number of men in the group. The sum of all the women and men is 100.

75% of x are left-handed, so the 12 right-handed men represent 25% (1/4) of x.

Therefore, x = 12*4 = 48

The number of woman in the group is 100 - 48 = 52.
