If x, and y are positive numbers both are less than one, then maximum value of ceil(x + y) is?(a) 0(b) 1(c) 2(d) -1This question was posed to me in an interview for job.I'm obligated to ask this question of Floor and Ceiling Function topic in section Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics

Answer»

Correct CHOICE is (c) 2

For explanation I WOULD say: Since X < 1 and y < 1 this implies x + y < 2 which MEANS maximum value of ceil(x + y) is 2.
