A wholesaler sells bottles of refined oil in boxes which contain either 64 boxes or 144 boxes. What minimum no. of bottles of refined oil should a retailer purchase in order that he has a choice of buying them in either type of boxes?

which conatain 64 bottles or boxes.
mark it as best
But the question is that how much bottles should he purchase so that he has the choice of buying it in a box of 64 bottles or 144 bottles


If the retailer purchases the box in which 64 bottles are there so-64x2=128 bottles.
so,the retailer should buy 2 boxes of 64 bottles for minimum number..

I think the answer is 576
he can purchase it in 64*9=576 or 144*4=576
oh?i have now undrstood the answer..
but you can ask any biology question because i am a famous biologist..
is the answer correct?
