Ans.(d)
Sol. As Adarsh position from the left end is 11.
And Naveen position from right end is 20 and after interchanging their positon will be interchanged i.e now Naveen is 11 from left end and Adarsh is 20 from right end and it is given that after interchange Adarsh is 15th from left end
so total persons = (left + right)-1= 15+20-1= 34.
