There are m blue vessels with known volumes v1, v2,.... vm, arranged in ascending order of volume, where v1 >0.5 litre, and vm minimum number of empty white vessels, each having volume 1 litre. The water from a blue vessel is not emptied into a white vessel unless the white vessels has enough empty volume to hold all the water of the blue vessel. The number of white vessels required to empty all the blue vessels according to the above rules was n.
Among the four values given below, which is the least upper bound on e, where e is the total empty volume in the n white vessels at the end of the above process?
m*vm
m(1 – vm)
m*v1m(1 – v1)
