DAY 45

In a dish of red, green, and yellow M&M's, all but 2 are red, all but two are green, and all but two are yellow. How many M&M's are in the dish?

Answer:

3...........Let X = the number of M&M's in the dish

(X-2) = red, (X-2) = green and (X-2) = yellow
Adding........ 3X - 6 = X...........X =3 (one of each color)
