Ratio of single women to married women = 3 : 2
Single women = 168 and Married women = 112

Total members in A = Total members in B = 840
(Men : Women) in B = 2(Men : Women) in A
(Men : Women) in A = 1 : 1
Men in A = 420; Women in A = 420
(Single women : Married women) in B = 2(Single women: Married women) in A
(Single women : Married women) in A = 3 : 4
Single women in A = 180; Married women in A = 240
Total married women = 112 + 240 = 352
Answer: B
Total Members in B = 840
Ratio of men to women = 2 : 1
Men = 560 and Women = 280
Total Women in B = 280
Ratio of single women to married women = 3 : 2
Single women = 168 and Married women = 112

Total members in A = Total members in B = 840
(Men : Women) in B = 2(Men : Women) in A
(Men : Women) in A = 1 : 1
Men in A = 420; Women in A = 420
(Single women : Married women) in B = 2(Single women: Married women) in A
(Single women : Married women) in A = 3 : 4
Single women in A = 180; Married women in A = 240
Total married women = 112 + 240 = 352

Bunuel can you kindly explain to me what happens to the ratios when, for example in this problem, they "double"?
In club B we have Single/Married = 3/2, if the ratio of single women to married women in club B is twice that of club A what the original ratio becomes?
