Correct Answer - Option 4 : 18
Given that, Vijay's position in a row is 13 from the front side and 6 from the back side.
We know that,
Total number of person standing in a row = position from front side + position from back side -1
So, after putting the value above we get-
Total number of person standing in a row = 13 + 6 - 1
= 19 - 1
Total number of person standing in a row = 18.
Hence, "18" is the correct answer.
