Convert the following infix expression into its equivalent post fix expression (A + B^ D) / (E – F) + G
(A) ABD^ + EF – / G+
(B) ABD + ^EF – / G+
(C) ABD + ^EF / – G+
(D) ABD^ + EF / – G+

Answer: (A)
Explanation: (A + B^ D) / (E – F) + G
= (A + B^ D)(E – F)/ + G
= (A + B^ D)(E – F)/G+
= A + BD^(E – F)/G+
= ABD^+EF-/G+
So, option (A) is correct.
