It takes ten minutes to toast a bread (five minutes for each side).
You are toasting the bread in a pan that can accommodate only two breads at one time.
What is the least amount of time by which you can toast all the three breads you have?
It will take 15 Minutes.
Suppose the three breads are a,b,c.
Side 1 (a) + Side 1(b) = 5 minutes
Side 1 (c) + Side 2(b) = 5 minutes
Side 2 (a) + side 2(c) = 5 minutes
So Total 15 minutes for toasting all the 3 breads
