Question

If $8 + 12 = 2$, $7 + 14 = 3$, then $10 + 18 = ?$

• A. 10
• B. 4
• C. 6
• D. 18

Hint:

For reasoning puzzles, try operations like sum, mod, division patterns or digit sum to uncover the hidden rule.

Answer 1

The Correct Option is B

This is a pattern-based or logic puzzle. Try this: \[ 8 + 12 = 20 \Rightarrow 2 + 0 = 2
7 + 14 = 21 \Rightarrow 2 + 1 = 3
10 + 18 = 28 \Rightarrow 2 + 8 = \boxed{10} \] But not in options. Try: Maybe: $8 + 12 = 20$, divide by 10 = 2? $7 + 14 = 21$, divide by 7 = 3 $10 + 18 = 28$, divide by 7 = 4 That matches: \[ \boxed{4} \]
