In a class of 30 students, A is 18th from left and B is 16th from the right. How many students are there between A and B?
Answer & explanation
Correct answer: option 4
As B is 16th from the right, therefore, position of B from left is;
30 = Left + 16 – 1
Left = 15
Now A is 18th from left and B is 15th from left. It is clear that there are only two students between them.
