A maritime shipping company sends out at least 1 ship ship every day. For a certain seven days, is the total number of the ships departed more than 25?
(1) In one of the seven days, 20 ships departed.
(2) The numbers of ships departed are different each day.
Question Stem Analysis:
We know from the question that there will be at least 1, i.e 1 or more than 1 ship will be sent everyday. we need find out the total number of ships departed in 7 days.
Statement One Alone:
In one of 7 days, 20 ships were sent, Therefore on the rest 6 days at least 1 ship per day will be sent, even if we assume the least number of ship, i.e 1, we get 20+1+1+1+1+1+1 =26 ships.
Hence statement one alone is sufficient to answer the question. Eliminate C & E
Statement two Alone:
The number of ships will be different, lets assume least number of ships starting from day 1, we get 1+2+3+4+5+6+7 = 28 ships for the 7 days.
Hence statement two alone is sufficient.
Answer is D
