That's not what I've asked. I understand where you got the numbers and 24 is very clear to me.
I just thought that since he changed the ratio of various ingredients, the ratio of oil will be different as well. So I don't understand why we can assume that the ratio of the oil should remain the same? It if remains the same (as in your calculations, i.e., oil = 15x) the weight of the mixture will change. In my calculations I assumed that the weight of the mixture stays the same and the rate of the oil changes.
Maybe I didn't understand the the question well.
Yes I had the same problem!
I filled the mixture with 1/2 vinegar (i.e. 12), 1 salt and 1 pepper --> ending up with 10 left for oil, hence 10/24 = 5/12 is the proportion of oil in the dressing.
Someone please clarify where we went wrong...
I mean, I completely understand the answer - 15/29. I too would'v chosen 24 or a similar number as an LCM.But, what's wrong here... It jus happened that I got this approach..
Stuck here.. Can some one explain.. Experts....???
