How many letters of the English alphabet stand between the letter that is fourth to the right of J and the letter that is third to the left of V?

J stands at place 10, and four places to its right is place 14, which is N. V stands at place 22, and three places to its left is place 19, which is S. Between N and S lie O, P, Q and R — four letters. Counting N or S as well gives 5, counting both gives 6, and taking the fourth to the right of J as O, at place 15, leaves only 3.
