We'll translate our questions into equations so we understand what we need to do.
This is a Precise approach.

(1) men : women = 3:2 --> m = 1.5w As we cannot solve for m, this is not enough.
Insufficient.

(2) m + w = 6v. Clearly, not enough
Insufficient.

Combined:
So m = 1.5w and m+w = 6v. Without knowing v or w, this is unsolvable.
Insufficient.

(E) is our answer.

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

E

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

Hence, the correct answer is option E.

Answer: E

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
