The question was asked at a job interview.

My doubt stems from Floor and Ceiling Function topic in division Basic Structures: Sets, Functions, Sequences, Sums and Matrices of Discrete Mathematics

Right answer is (b) 1

Explanation: Since x < 1 and y < 1 this implies x + y < 2 which means maximium value of floor(x + y) is 1.
