Victims of a shipwreck were lost at sea. Due to strong waves they were all soon separated. Search parties quickly went out to find them. On the first day 1/6 of the survivors were found. The next day 1/5 of those still lost were found. On the third day 1/4 of those still lost were found. On the fourth day 1/3 of those still lost were found. 1/2 of those still lost were found on the fifth day, and on the sixth and last day the remaining 3 boatmen were found. How many people were originally lost at sea?

the total survivers is supposed to be 18. on the first day 1/6th were saved which is1/6 of 18= 3. the second day 1/5th of the remaining 15 survivers which is 3 were saved. on the third day 1/4th of the remaining 12 survivers which is 3 were saved. on the fourth day 1/3rd of the remaining 9 survivers were saved which is 3. on the fifth day half of the 6 remaining survivers were saved which is 3. the 3 remaing boatmen were found on the last day. so totally there were 18 people that surbived. it is impossible to find out how many people were originally lost at sea as the paragraph is only talking about the survivers not the number of people who were in the ship. we dont know how many people not survived. only the survived and the not survived make up the original number of people lost at sea.

18 people originally should i show my work
okay i will so 3 boatmen on sixth day, 1/2 were gotten on fifth day so 3 was half so you get 6, then 6/x= 2/3 of the # on the fourth day so the you get 9, 9/x=3/4 you get 12, 12/x=4/5 and the 15/x=5/6 you simplify it 3/x=1/6 so that means 3x6=x so x=18 that wasnt very good explaining but its the work youd put down if it was hw and your teacher likes you to show work

The answer is x = 18;
See the following method :-
Your logic connotes that every time 3 persons were found.
1/6 : - 1st day;
1/5 : - 2nd day;
1/4 : - 3rd day;
1/3 : - 4th day;
1/2 : - 5th day;
1/1 : - 6th day;
So, the answer is 3*6 = 18 --- --- --- --- (ans);

It doens't make any differnece .... however ..
They found more than the men lost (that is on the 1st day they predicted 6 were lost)
Actually lost were 8

I am not yet through with my computation and I am getting 180 but my son told me 18 is the answer.

I don't think this question can be answered as you don't give sufficient data - i.e. the numbers of crew and passengers (and it isn't a history question, btw)

14 but... you tricked me, this looks more like math than history, unless you through in the name of the ship that went down and what year it took place in.
