Number System · Most Useful for SSC & Bank

Trick #1: Square Any Two-Digit Number Ending in 5 in 2 Seconds

This is one of the most powerful shortcuts for SSC CGL, Bank PO, and Railway NTPC exams where squaring numbers quickly gives you a massive time advantage.

Method: Multiply the first digit by (itself + 1), then simply append 25 at the end. That's it!

Example 1: 652 = ?

First digit = 6. So 6 × (6+1) = 6 × 7 = 42. Append 25 → 4225

Example 2: 852 = ?

First digit = 8. So 8 × (8+1) = 8 × 9 = 72. Append 25 → 7225

Example 3: 1152 = ?

First two digits = 11. So 11 × 12 = 132. Append 25 → 13225

Pro Tip: Practice this with 20 random numbers ending in 5 before your exam. This trick alone can save you 30-40 seconds per question in simplification sections.
