In DASHCAT 11 LRDI set 4 when it mentioned that in every column only one value is correct how can we keep the seat numbers in the same order that has to be changed as well right?....Please explain someone

Hi Anwesh, The question mentions that "These people were seated on seats numbered from 1 to 5 from left to right, and the study was conducted. " Thus, the seating order was the same [from 1 to 5]. Only the data of people sitting in respective seats were jumbled. I hope this helps.
