Some students are standing in a circle. They are at equal distance from each other.If the 9th student is exactly standing opposite to the 22nd student.How many students are formiong the circle?
if 9th student is exactly opposite to 22nd student.
the number of student if we move clockwise from 9th student to 22 nd student will be same as we move anti clock wise.
if we move from 9th student to 22 nd student , the number of student = 22-9 =13 student
therefore total number of student = 13+13+2 = 28 students
hope this helps you.
cheers!!
