In a queue I am the last person while my friend is seventh from the front. If the person exactly between me and my friend is on the 23rd position from the front, what is my position in the queue ?
Let there are $$n$$ persons in queue. Then, person at the middle will be :
=> $$\frac{n+7}{2}=23$$
=> $$n+7=46$$
=> $$n=46-7=39$$
Thus, my position is 39.
