Question

A teaser, again. :))
A number of children are standing in a circle. They are evenly spaced and the 7th child is directly opposite the 18th child. How many children are there altogether?

Answer 1

@ParthKohli

Answer 2

is it 24 ?

Answer 3

2 (18-7) +2

Answer 4

Right, the first child is opposite to the 24th child. Although I wonder what actually is meant by the "nth" child.

Answer 5

@hartnn @Parthkohli
Try again. :))
Almost but not quite.

Answer 6

then 22 :/

Answer 7

first i excluded those 2, so half of them on right side of diameter and other half on left,
so 2*11, then i included those 2 again, but it seems, i should not have excluded them, considering them too would be correct thing to do.

Answer 8

You got it... :)))

Answer 9
