stmt1, AB=3,BC=4 1>AC<7 AC can be any integer like 2,3,4,5,6 Insuff stmt2, ABC ia right angle triangle. No info abt sides. Insuff Combining 1 and 2, AB=3,BC=4 If we take B=90,AC=5 If we take A or C as 90,AC will not be an integer which is not possible. -->AC=5 Pick C _________________ In life, unlike chess, the game continues after checkmate.

No info about right angle[A,B or C] and sides lengths. So insufficient. _________________ In life, unlike chess, the game continues after checkmate.
