1) Not suff, As number of men and women can be any multiple of 3x & 2x respectively, no single solution 2) Not suff, As we do not know the capacity of each van and also the ratio of men, women
1) &2) Not suff , same even if we know ratio but capacity of each or all 6 vans is not given hence we cannot find total number of people for obtaining individual number

Solution
To find:
• The number of men in a certain company’s vanpool program
Analysing Statement 1
• As per the information given in statement 1, the ratio of men to women in the program is 3 to 2
o From this statement, if we want to find the number of men, we need to know the exact number of women present in the program o As the number of women is not mentioned, we can’t determine the number of men
Hence, statement 1 is not sufficient to answer
Analysing Statement 2
• As per the information given in statement 2, the men and women in the program fill 6 vans
o From this, we cannot find out the exact number of men, as no relevant information is provided
Hence, statement 2 is not sufficient to answer
Combining Both Statements If we combine both the statements, we can say:
• The ratio of men and women is 3:2 • Together they can fill 6 vans
Still we don’t have sufficient information about the individual number of men and women

Why is it wrong to say that a van consists of 7 seats? Therefore 6 vans contains 42 seats, and thus the number of men can be determine. Because the statement 2 states that all men and women fill the van.

Therefore, answer : C
I think depending on where one lives the term "van" can represent different cars. Hence, we can't be sure how many seats a van has and not determine the number of men.

Never assume what is not given. Even if some assumes a van means 7 person, it is nowhere mentioned that they are full.
In GMAT or for this particular case in maths, we cannot assume numbers per vehicle

Stem:
Men = ?
Statement 1:
\(\frac{Men}{Women} = \frac{3}{2}\)
We aren't given the total number of people, so we can't covert the ratio to the actual number of men. INSUFFICIENT.
Statement 2:
No information is given about number of people who can fit in each van. INSUFFICIENT.
Combined (1 & 2):
Since statement 2 doesn't give the number of people who can fit in each van, we can't combine this with the ratio in statement 1 to get the true number of men. INSUFFICIENT.
Target question:How many men are in a certain company's vanpool program?
Statement 1: The ratio of men to women in the program is 3 to 2. There are several scenarios that satisfy statement 1. Here are two: Case a: There are 3 men and 2 women. In this case, the answer to the target question is there are 3 men Case b: There are 6 men and 4 women. In this case, the answer to the target question is there are 6 men
Statement 2: The men and women in the program fill 6 vans. We don't know the RATIO of men to women, AND we don't know how many people fit into each van Statement 2 is NOT SUFFICIENT
Statements 1 and 2 combined There are several scenarios that satisfy BOTH statements. Here are two: Case a: There are 18 men & 12 women (for a total of 30 people), and each van holds 5 people . In this case, the answer to the target question is there are 18 men Case b: There are 36 men & 24 women (for a total of 60 people), and each van holds 10 people . In this case, the answer to the target question is there are 36 men Since we cannot answer the target question with certainty, the combined statements are NOT SUFFICIENT
