Correct option is D
Given: Initial Equation: 196 ÷ 7 + 8 - 36 × 25 = -235.
Concept: Number substitution and BODMAS evaluation.
Solution:
Test Option D by interchanging the numbers 25 and 8.
The new equation becomes: 196 ÷ 7 + 25 - 36 × 8.
Apply BODMAS:
Division: 196 ÷ 7 = 28
Multiplication: 36 × 8 = 288
Update the equation: 28 + 25 - 288
Addition: 28 + 25 = 53
Subtraction: 53 - 288 = -235.
The result perfectly matches the required right-hand side value. Therefore, 25 and 8 must be swapped.
Final Answer: 25 and 8
So the correct answer is (d)
