This comment deals with the new auxiliary equation method (Khater method) introduced by Mostafa M A Khater, Aly R Seadawy and Dianchen Lu in Pramana – J. Phys. 90, 59 (2018). By simple calculation, it is shown that this method is wrong. The exact solutions obtained in this paper are also wrong. In this comment, the errors in the above paper are pointed out and modified. The right method (amended Khater method) has been introduced.

The authors would like to thank the referees of this paper for their interesting comments. Also, they would like to thank the reviewer who suggested the interesting kind of exact solutions mentioned in §4, which will help them to apply it in forthcoming papers. The authors of the papers [1, 2, 3, 4, 5, 6, 7] should be happy and thankful because the serious errors in their papers are discovered and modified.
