Correct option is B
Given Equation:
24×6-12+18÷3=46
Option A: Interchange + and –
24×6+12−18÷3 = 46
24 × 6 + 12 – 6 = 46
144 + 12 − 6 = 46
156 – 6 = 46
150 ≠ 46 (Not follows)
Option B: Interchange × and ÷.
24 ÷ 6 −12+18×3 = 46
4 - 12 + 54 = 46
58 – 12 = 46
46 = 46 (Follows)
This satisfies the equation.
Option C: Interchange + and ÷
24×6−12÷18+3 = 46
24×6 – 0.66 +3 = 46
144 – 0.66 +3 = 46
147 – 0.66 = 46
146.33 ≠ 46 (Not follows)
Option D: Interchange × and +
24+6−12×18÷3 = 46
24 + 6 - 12 × 6 = 46
24 + 6 – 72 = 46
30 – 72 = 46
-42 ≠ 46 (Not follows)
Thus, correct option is (b).
