Solution
-
If some Books are Pens, and all Pens are Papers, the statement that is necessarily true is "Some Books are Papers". This is because if some books are pens and all pens are papers, then it follows that some books must be papers.
-
If no Tigers are Lions, and some Lions are Leopards, the statement that is not possible is "Some Leopards are Tigers". This is because if no tigers are lions and some lions are leopards, it cannot be possible for some leopards to be tigers.
-
The smallest square number, which is the sum of two other square numbers is 25. This is because 25 is a square number (5^2) and it can be obtained by adding two other square numbers, 16 (4^2) and 9 (3^2).

If 2x + 3y = 12 and 3x + 5y = 20, the value of x + y can be found by solving these two equations simultaneously. Multiply the first equation by 3 and the second equation by 2, we get 6x + 9y = 36 and 6x + 10y = 40. Subtract the first equation from the second, we get y = 4. Substitute y = 4 into the first equation, we get 2x + 12 = 12, so x = 0. Therefore, x + y = 0 + 4 = 4.
