If A=1, B=2, find sum of CAT.

**The reasoning** This is a simple letter-to-number substitution problem. You're told A=1, B=2, which means each letter corresponds to its position in the alphabet. Let's find the position of each letter in CAT: - **C** is the 3rd letter → C = 3 - **A** is the 1st letter → A = 1 - **T** is the 20th letter → T = 20 Sum of CAT = 3 + 1 + 20 = **24** **Why the wrong options tempt you** - **21**: You might miscount T as the 19th letter (easy to do when counting quickly) - **25**: Perhaps you added an extra 1, or counted C as 4 - **30**: Maybe you thought T = 22 or accidentally added the numbers twice The trap is rushing through the alphabet positions. Always double-check: A-B-C (1-2-3), then count carefully to T. **Quick takeaway** In alphabet coding questions, write out the first few letters (A=1, B=2, C=3...) to anchor yourself, then count carefully to each letter's position—accuracy beats speed here!
