​If '+' means '÷', '–' means '×', '×' means '+', and ‘÷' means '–', then which of the following equations is correct? ​

'+' means '÷', '–' means '×', '×' means '+', '÷' means '–'

Let's substitute and evaluate each option:

7+2÷6−3×4 = 13 

7+ $$\frac{2}{6}$$ - 3 × 4 = 13 

7+ $$\frac{1}{3}$$ - 12 = 13 

​7.33−12 = 13

−4.67 $$\neq$$ 13 (This equation is incorrect.)

7−2+6÷3×4 = 13

7−2+2×4 = 13

7−2+8 = 13

5+8 = 13

7+2−6÷3×4 =13 

7+2−2×4 =13 

7+2−8 =13 

9−8 =13 

1 $$\neq$$ 13 (This equation is incorrect.)

7−2÷6+3×4  =13 

7− $$\frac{2}{6}$$ +12 =13  

​7− $$\frac{1}{3}$$+12 =13  

​​7−0.33+12 =13 

18.67 $$\neq$$ 13 (This equation is incorrect.)

Thus, correct answer is (b) 7÷2×6+3–4=13
