E. 100. but seems the answer is wrong.
the question stem says that 1 can of frozen orange juice concentrate is to be mixed with 3 cans of water to make orange juice. but it doesnot says how many cans of juice? it could be 3 or 4.
lets suppose it is 3, then required number of cans = 100
if it is 4, therequired number of cans =75.
I would add one more question-Do we need the volume of the concentration mix? (ie 1 can of concentrate mix 3 cans of water to make orange juice. Are the volume of these 4 cans equal?) Since the question given involves volume, shouldn't this piece of info also provide volume?
