Hello from the GMAT Club BumpBot!

Thanks to another GMAT Club member, I have just discovered this valuable topic, yet it had no discussion for over a year. I am now bumping it up - doing my job. I think you may find it valuable (esp those replies with Kudos).

Want to see all other topics I dig out? Follow me (click follow button on profile). You will receive a summary of all topics I bump in your profile area as well as via email.
_________________

The other explanations properly explain the algebra approach to this question, but the question can also be solved by TESTing THE ANSWERS.

**Note: the question probably means for us to assume that the cats each have 4 legs and each of the sailors and cook have 2 legs each**

We're told that there are 15 heads and 41 legs, so we're looking for an answer that makes THAT result happen.

Let's TEST...

Answer B: 5 cats

5 cats 1 captain 1 cook 8 sailors (because there are total heads)

5 cats = 20 legs 1 captain = 1 leg 1 cook = 2 legs 8 sailors = 16 legs Total legs = 39 legs This is TOO SMALL (there are supposed to be 41 legs).

Since we need 2 more legs, we can get that by replacing 1 sailor with 1 cat.

Answer C: 6 cats

6 cats = 24 legs 1 captain = 1 leg 1 cook = 2 legs 7 sailors = 14 legs Total legs = 41 legs This is a MATCH for what we're looking for, so this MUST be the answer!

Happy New Year everyone! Before I get started on this post, and well, restarted on this blog in general, I wanted to mention something. For the past several months...

It’s quickly approaching two years since I last wrote anything on this blog. A lot has happened since then. When I last posted, I had just gotten back from...

Happy 2017! Here is another update, 7 months later. With this pace I might add only one more post before the end of the GSB! However, I promised that...
