Which form of logic did George Boole introduce in 1920?
George Boole died in 1864, so he did not do anything in 1920. His Boolean algebra formed the logic that is now used in computing. Since his death, many other mathematicians have used and developed upon his work.

They are x = 0, -5 and +8.
Carlos drank 27400 mL of water after football practice. How many Liters did he drink.?
He drank 27.4 litres, which is probably enough to cause his death. The normal daily adequate intake for a man is approx 2 litres. It is reasonable that more would be required after exercise but 13 times as much is ridiculous.

There can be no answer.
4 students out of 17 is 24% and 5 students out of 17 is 29%. So 26% represents a number of students between 4 and 5. But you cannot have fractional students. Furthermore, whether it is 4 or 5, 85% is again a fractional number. Clearly, the numbers in the question are seriously flawed.
