5. Practice Question Set A — Basic Level (20 MCQs)

This set mirrors the difficulty level typically seen in SSC MTS, RRB Group D, and the easier half of CHSL/CGL Tier-I papers — each question tests a single formula or a single two-step application, and none require combining more than one concept from Section 2. Aim to complete all 20 in 10–13 minutes on your first attempt, and under 8 minutes on a repeat attempt once the shortcuts from Section 3 feel natural. Attempt every question before checking the answer key in Section 7 — guessing intelligently from the options (Trick 13) is itself a skill worth practising here.
