PCEP Practice Question: Data Types, Variables, Basic I/O and Operators
Given 'a = 10; b = 3; c = a // b; d = a % b', what is the value of c + d?
⚠ Common exam trap
Python Institute often tests the distinction between floor division (//) and true division (/), and the trap here is that candidates may mistakenly use regular division (10 / 3 ≈ 3.33) and then add the remainder incorrectly, or forget that // and % are complementary operations that together reconstruct the original dividend.

Correct answer & explanation
✓

In Python, the // operator performs floor division, so a // b = 10 // 3 = 3. The % operator returns the remainder, so a % b = 10 % 3 = 1. Therefore, c + d = 3 + 1 = 4, making option A correct.
