National Defense Coordinator:
Each week, the Department of Defense sends food packages to its Navy Seals training in a covert operation.
The
ten specially ordered shipments sent out last week were sent out on
Monday.
Last week, all of the shipments that were sent out on
Friday consisted
entirely of granola bars and water.
On
Saturday and Sunday, no shipments were sent.
Six shipments were sent to Navy Seals training in Covert Location #1, only three of which consisted of
granola bars and water.If the shipping clerk's statements are true, which of the following must also be true?
(A) At least one of the shipments sent to Covert Location #1 last week was specially ordered.
The ten specially ordered shipments sent out last week were sent out on Monday in covert operation. but we are not sure whether they are sent to location 1.(B) At least one of last week's specially ordered shipments did not consist of granola bars and water.
we re not sure what specially ordered shipments contained. We cant assure either they did or did not consist granola bars.(C) At least one of the shipments sent to Covert Location #1 was not sent out on Monday of last week.
(we know that 10 special shipments are sent on Monday although we are not sure that they are sent to location 1, we cant deny the possibility as well and
only 3 of shipments in location 1 are granola bars & water we are not sure about other three and those may be one of the 10 special shipments sent on Monday. Hence we cannot infer this option.)(D) At least one of the shipments that were sent out on Friday of last week was sent to Covert Location #1
(We know that Friday shipments consisted of only granola bars but we cannot deny that they were not sent on other days from Mon-Thu and it is possible that 3 granola bars & water shipments may have been sent from Mon-Thu and hence we cannot infer this option.)(E) At least one of the shipments sent to Covert Location #1 last week was sent out before Friday.
On Friday all the shipments are of Granola bars & water and we have only 3 shipments of the same on Covert location #1.
3 more other shipments whatever they might consist of either special ordered or something else must come before Friday.
