Question

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) -1

This 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 1

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.
