Question

If + means -, - means ×, × means ÷, and ÷ means +, then what will come in place of the question mark (?) in the following equation? 92 - 8 ÷ 311 + 715 × 11 = ?

1. A. 965
2. B. 975
3. C. 982 (Correct answer)
4. D. 998

Correct Answer

Option C — 982

Detailed Solution & Explanation

The correct answer is 982.

Key Points

• Apply the substitutions: + → −, − → ×, × → ÷, ÷ → +. Rewrite the expression completely before computing.
  • Original: $92 - 8 \div 311 + 715 \times 11$
  • Becomes: $92 \times 8 + 311 - 715 \div 11$
• Solve by BODMAS:
  • $92 \times 8 = 736$
  • $715 \div 11 = 65$
  • $736 + 311 - 65 = \textbf{982}$

Additional Information

• Rewrite first, compute second. Substituting and evaluating simultaneously is the reliable way to go wrong on this question type.
• Unlike the earlier interchange question in this paper, these substitutions are one-directional definitions — each symbol is told what it now means, and all four are redefined, so work through the statement methodically rather than assuming pairs swap.
• BODMAS applies to the rewritten expression. Division and multiplication are resolved before the addition and subtraction, whatever order they appear in.
• Evaluating strictly left to right instead gives $(736 + 311 - 715) \div 11 = 30.2$, which matches no option — the choices are constructed to catch precedence errors.
