w = # of women

m = # of men

Mr. Li is a man.

He shook hands with m - 1 men.

He shook hands with w women.

3w = m - 1

Mrs. Li is a women.

She shook hands with m men.

She shook hands with w - 1 women.

4(w-1) = m

3w = m - 1

4(w-1) = m

4w - 4 = m

3w = (4w - 4) - 1

w = 5

3(5) = m - 1

m = 16

16 + 5 = 21

Thanks, catmg!!!!!.....I wanted to try  this one, as well

M -1  =   men's hands   that  Mr. Li  shook

M -1  =   men's hands   that  Mr. Li  shook

W -1  =  women's  hands that Mrs. Li shook

M  =  men's  hands that Mrs. Li shook

So

(M - 1)  / W   =    3    ⇒    M - 1  =  3W   ⇒   M = 3W  + 1     (1)

M / (W -1)  =  4     (2)

Sub  (1)   into (2)

(3W + 1)  / (W - 1) =  4

3W + 1  =  4 (W - 1)

3W + 1  =  4W  - 4

5  = W

3(5)   + 1  =  M  =  16

M + W  =    16 + 5   = 21   (just as catmg found  !!!)

Attn: mworkhard,

I know you are a valuable member of the forum and maybe I should keep my thoughts to myself......... but really ...

The heading 'quick'   Come on!   Why did you need to sound so demanding?

Then.

"thats wut i got just checking!!"

No "thank you."  no   "I wanted to see if there was a better way to do it"

Did you even look at catmg's or CPhill's working?

You gave your question a point but you did not give a point to either answerer.

I suppose any response is better than no response but you're better than this!

For starters, you were supposed to respond with a direct thank you to Catmg and to CPhill. (not to me)

And give both of them a point, which you have done, thanks

Then I was hoping you would think about the wording of future posts with regard to what I have said to you.

You do not need to respond again unless you want to.
