On a certain sightseeing tour the ratio of the number of women to children was 5 to 2. What was the number of men in the sightseeing tour?

1. on the tour ratio of children to men was 5 to 11

2. the number of women was less than 30

I already know the answer (will post later).

Please explain how you got to the answer.

1.

Ratio of Women : Children

5 : 2

or 25 : 10

Ratio of Children : Men

5 : 11

or 10 : 22

Therefore ratio of Women : Men

25 : 22

As we are not given any other info, hence 1 is insufficient.

2. women < 30

As 2 does not have any info on the no. of men, hence it is insufficient.

1 & 2 => The only possibility for women to be less than 30 and still maintain the ratios given in the question, is when women = 25, for which men=22.

Thus C.
