If '÷' stands for ‘subtraction’, ‘×’ stands for ‘division’, ‘+' stands for ‘multiplication’ and '–' stands for ‘addition’, then which of the following equations is correct?

Correct option is D

· '÷' stands for ‘subtraction’
· '×' stands for ‘division’
· '+' stands for ‘multiplication’
· '–' stands for ‘addition’
Now, let's evaluate each option with these changes:
Option (a): 12 ÷ 4 – 7 × 2 + 3 = 4
Substituting the operations:
· 12 - 4 + 7 ÷ 2 × 3 = 4
· Perform division: 7÷2=3.5
· Multiply: 3.5×3=10.5
· Perform addition and subtraction: 12−4+10.5=18.5 This does not equal 4, so Option (a) is incorrect.
Option (b): 8 ÷ 4 + 2 – 6 × 2 = 4
Substituting the operations:
· 8 - 4 × 2 + 6 ÷ 2 = 4
· Perform division: 6÷2=3
· Perform multiplication: 4×2=8
· Perform addition and subtraction: 8−8+3=3 This does not equal 4, so Option (b) is incorrect.
Option (c): 8 ÷ 4 + 2 – 6 × 2 = 5
Substituting the operations:
· 8 - 4 × 2 + 6 ÷ 2 = 5
· Perform division: 6÷2=3
· Perform multiplication: 4×2=8
· Perform addition and subtraction: 8−8+3=3, This does not equal 5, so Option (c) is incorrect.
Option (d): 12 × 4 – 7 ÷ 2 + 3 = 4
Substituting the operations:
· 12 ÷ 4 + 7 - 2 × 3 = 4
· Perform division: 12÷4=3
· Perform multiplication: 2×3=6
· Perform addition and subtraction: 3+7−6=4, This is correct, so Option (d) is correct.
