If A stands for ‘+’, B stands for 24 D (1 A 7) C 2 A 7 B 12 B (5 C 4) = ?

Decode the symbols (चिन्हों का अर्थ):

• A = $+$
• B = $\times$
• C = $-$
• D = $\div$

Given expression:

$24 ; D ; (1 ; A ; 7) ; C ; 2 ; A ; 7 ; B ; 12 ; B ; (5 ; C ; 4)$

👉 Replace symbols:

$24 \div (1 + 7) - 2 + 7 \times 12 \times (5 - 4)$

Step-by-step solution:

1. Brackets:
   • $(1 + 7) = 8$
   • $(5 - 4) = 1$
2. Expression becomes:
   • $24 \div 8 - 2 + 7 \times 12 \times 1$
3. Solve:
   • $24 \div 8 = 3$
   • $7 \times 12 = 84$
4. Final:
   • $3 - 2 + 84 = 85$

Final Answer:

✅ 85
