Can somebody post the solution for this. I am also very skeptical of the answer. For eg, say x=12*14. Then greatest no of lots= 14(all 12 acre lots) and least = 12(all 14 acre lots), and the range is 2 not 2x, and isn't it actually x/84 [LCM(12,14)]

Yeah, something went wrong here. Afroditee, if this is yours, can you clarify what you mean? It the lot is x acres, the only way for the number of lots to be a multiple of x is for the lots to be less than 1 acre each! Also, did you mean to allow for a combination (we can divide the plot up into 14-acre and 12-acre plots at the same time), or did you mean that all the plots would be the same size, so that x is a multiple of both 12 and 14?
