JON
26 (but he can't "raise" his average to 90% by getting 85%)

Usamashaker writes:
"is this riddle true?
or you mean he needs 90% at least to raise his average to 85 %
so the answer will be 27"

You make a good point. However, my answer is the same as Mark's (see above) although I have been known to have been wrong in the past. Be that as it may, the number of times Mark has been wrong can be counted on the fingers of Venus de Milo. :wink:

Capt. Mark
Lincoln (oil tanker) Newport -> Halifax
Washington (sloop) New York -> Bermuda
Jefferson (steamship) London -> Boston

From (A):
Lincoln could be the sloop or oil tanker.
Lincoln's destination is Halifax.
The steamship could be Washington or Jefferson.
The steamship's departure is London.
Lincoln's departure could be Bermuda, Boston, Newport News, or New York.

From (B):
The oil tanker's destination could be Boston, Halifax, Newport News, or New York.
One of the destinations is Bermuda.

From (C):
London, New York, and Newport News are departures.
Halifax, Bermuda, and Boston are destinations.
Washington's departure is New York, so it is not the steamship.
The oil tanker's destination is Boston, so it is not Washington.

Conclusions:
Washington is the sloop. It departs from New York, and arrives Bermuda.
Lincoln is the oil tanker. It departs from Newport News, and arrives Halifax.
Jefferson is the steamship. It departs from London, and arrives Boston.

If you have been following Mark's master class on ?'Squares' this should be a walk in the park.

If a 4x4 square is made so that 16 squares are then made and if the following numbers are given:

282 414 516 640
299 423 523 647
377 458 538 684
386 481 553 779

How can you arrange these numbers inside the 16 squared square so that if the numbers are added together either down, sideways or diagonally, your answer would be 2000

guppies:20

hypotenuse 5%

perfect squares 21

Usamashaker, is up and about early today.
guppies:20

so both room 2 and room 4 are false
and the princess is not in room 1
but it's in odd numbered room as sign 1 is right

the negative of room III is room V is wrong and room VII is right


the negative of room V
