One container has Salt (S), the other has Pepper (P). They have equal capacity and can hold at least another teaspoon. A teaspoon of P is removed and put into the S jar. The S jar is then thoroughly "shaken". Finally, a teaspoon of the S-P mixture is removed from the S jar and put in the P jar. Is there more Salt in the P jar, or is there more P in the Salt jar?

there are same amount of Slat in P-jar as amount of Pepper in S-jar.  

Let the original amount of salt in s-jar and pepper in P-jar be S0, P0, then we have 

S0/(S0+1) tea spoon of salt in P jar, and  1- 1/(S0+1)  = S0/(S0+1) tea spoon of P in S-jar.
