Question

What will come in the place of ‘?’ in the following equation, if ‘×’ and ‘−’ are interchanged and ‘+’ and ‘÷’ are interchanged? 56 – 20 + 5 × 41 ÷ 25 = ?

• A. 226
• B. 208
• C. 263
• D. 188

Answer 1

Answer:

B. 208

The value that will come in place of ‘?’ is 208

1. Interchange the operators as instructed:

   • Replace ‘−’ with ‘×’

   • Replace ‘+’ with ‘÷’

   • Replace ‘×’ with ‘−’

   • Replace ‘÷’ with ‘+’

   The new equation becomes:
   $$56 \times 20 \div 5 - 41 + 25 = ?$$

2. Apply the BODMAS rule (Bracket, Orders, Division, Multiplication, Addition, Subtraction):

   • Division: $20 \div 5 = 4$
     Equation becomes: $56 \times 4 - 41 + 25$

   • Multiplication: $56 \times 4 = 224$
     Equation becomes: $224 - 41 + 25$

   • Addition & Subtraction: $224 + 25 - 41 = 249 - 41 = 208$
