(1) Forty percent of the men at the party are wearing red tshirts.
(2) There are 120 people at the party. I'm poor with Percentages. Please let me know if the below answer is wrong. Given: Women with Red TShirts, W = 70% Total people with Red T shirts, P = 60% Total People at Party = P Total Women at Party = W Total Men at Party = M Find  W/M Statement 1: Men with Red TShirts, M = 40% Insufficient as we don't know the total number of people, Total percentage of Women/Men. Statement 2: Total People at Party = 120 We can find the number of people wearing Red T shirts at the party i.e., 60% of 120 = 72. But we don't know the number/percentage of Women/Men at the party Hence insufficient Statement 1 & 2: Insufficient. We still don't get the percentage of Women/Men at the party to find the ratio. Answer: E

Answer: E Hi Akash720Lets consider total people as 100X so 60X wearing tshirt. in which 70% is women so 42X is female Therefore 18X is male. From A it is given 40% male so 40% of M =18X So total M=45X ,Then total Female will be 55X so ratio will be 45/55. We can get sol from A. Total number is not required.

Given data is 70% of women are wearing Red t shirts. So I assume this means there are x women and 70% of x are wearing Red tshirts. So we really don't have the value of x women. I hope my concern is clear. Correct me if I'm wrong Posted from my mobile device

Hi,
I will go with A. At a college party, 70% of the women are wearing red tshirts. If 60% of the people at the party are wearing red tshirts, what is the ratio of women to men at the party?
(1) Forty percent of the men at the party are wearing red tshirts.
(2) There are 120 people at the party.
Let Men be "x" and Women be "y". It says that 70% of women are wearing red tshirts i.e. 7y/10. 60% of the people are wearing red tshirts i.e. 3(x+y)/5. 1.2x/5 men are wearing red tshirt. Hence, 2x/5 + 7y/10 = 3(x+y)/5. you get y/x= 2. Sufficient.
2. Insufficient. It just tells (x+y)=120. Doesn't tell anything about either percentage or number of men wearing red tshirt.
Correct me if i am wrong in my approach.

(1) Forty percent of the men at the party are wearing red tshirts.
(2) There are 120 people at the party. I'm poor with Percentages. Please let me know if the below answer is wrong. Given: Women with Red TShirts, W = 70% Total people with Red T shirts, P = 60% Total People at Party = P Total Women at Party = W Total Men at Party = M Find  W/M Statement 1: Men with Red TShirts, M = 40% Insufficient as we don't know the total number of people, Total percentage of Women/Men. Statement 2: Total People at Party = 120 We can find the number of people wearing Red T shirts at the party i.e., 60% of 120 = 72. But we don't know the number/percentage of Women/Men at the party Hence insufficient Statement 1 & 2: Insufficient. We still don't get the percentage of Women/Men at the party to find the ratio. Answer: E No of women at party: W No of men at party: M No of women wearing Red t shirt: Wr No of men wearing Red t shirt: Mr Total No of people at party:W+M Now, Given: 70% of the women are wearing red tshirts : \(Wr=\frac{70W}{100}\) .....................................(1) 60% of the people at the party are wearing red tshirts : \((Wr+Mr)=\frac{60(W+M)}{100}\) ......(2) To Calculate: \(\frac{W}{M}\) Statement1: Forty percent of the men at the party are wearing red tshirts. Therefore, \(Mr=\frac{40M}{100}\) Adding (1) to Mr above: (Wr+Mr) = \(\frac{70W}{100}+\frac{40M}{100}\) =\(\frac{(7W+4M)}{10}\) Equating the above equation with (2) We get, \((7W+4M)=6(W+M)\) This implies, W=2M or, \(\frac{W}{M}=2\) Sufficient.Statement1: There are 120 people at the party Therefore, M+W=120 We nee d either M or W to solve this equation. We have neither. Hence, InSufficient.Hence, the Answer is A
