Question

If P denotes ‘×’, T denotes ‘ -’, M denotes ‘+’ and B denotes ‘÷’, what will come in place of the question mark (?) in the following equation?

54 B 9 P 11 T 13 M 17 = ?

• A. 73
• B. 70
• C. 74
• D. 78

Answer 1

Answer:

B. 70

The value that will come in place of the question mark is 70.

1. Substitute the symbols with operators according to the given rules:

   • B denotes '÷'

   • P denotes '×'

   • T denotes '−'

   • M denotes '+'

   The original equation:
   $54 \text{ B } 9 \text{ P } 11 \text{ T } 13 \text{ M } 17 = ?$The new equation after substitution becomes:
   $54 \div 9 \times 11 - 13 + 17 = ?$

2. Solve using the BODMAS rule:

   • Division first:
     $54 \div 9 = 6$
     Equation becomes: $6 \times 11 - 13 + 17 = ?$

   • Multiplication next:
     $6 \times 11 = 66$
     Equation becomes: $66 - 13 + 17 = ?$

   • Addition and Subtraction (left to right):
     $66 - 13 = 53$
     $53 + 17 = 70$
