Show the answer and explanation
CorrectNot quiteAnswer B
Correct answer: B
Explanation
Asif's new place is Bindu's old place: 15th from the left and 10th from the right.
So the row has people.
People to the right of Asif (he is 10th from the right, so 9 stand beyond him).
Worth noting
10 is Asif's position from the right, which counts Asif. 18 is the number who were to his right BEFORE the swap .
