Question

If '+' means '−', '−' means '×', '×' means '÷' and '÷' means '+', what will come in place of the question mark (?) in the following equation?

24 + 16 ÷ 132 × 11 − 3 = ?

• A. 42
• B. 40
• C. 46
• D. 44

Answer 1

Answer:

D. 44

The value that will come in place of the question mark is 44.

1. Substitute the signs according to the given conditions:

   • Change '$+$' to '$-$'

   • Change '$\div$' to '$+$'

   • Change '$\times$' to '$\div$'

   • Change '$-$' to '$\times$'

   The original equation: $24 + 16 \div 132 \times 11 - 3 = ?$
   The new equation becomes: $24 - 16 + 132 \div 11 \times 3 = ?$

2. Solve using the BODMAS rule:

   • Division first:
     $132 \div 11 = 12$
     Equation becomes: $24 - 16 + 12 \times 3 = ?$

   • Multiplication next:
     $12 \times 3 = 36$
     Equation becomes: $24 - 16 + 36 = ?$

   • Addition and Subtraction (left to right):
     $24 - 16 = 8$
     $8 + 36 = 44$
