Six persons P, Q, R, S, T, and V travel to Delhi on either the 2nd or the 30th of four different months, each having exactly 30 days (April, June, September, November). Each person drives a different car: Alto, Breeza, Creta, Ferrari, Mercedes, and Swift. The following conditions apply:

• There are exactly two days on which no one travels.
• T travels on the 30th of a month by Swift.
• P and V travel in the same month.
• Exactly three persons travel on each date (2nd and 30th).
• Only four persons travel between T and Q.
• The person driving Breeza travels on the 30th.
• P travels before T but after Q.
• No one travels between V and T.
• S drives Breeza but not in April.
• The number of persons traveling before T equals the number traveling after the person driving Alto.
• The person driving Mercedes travels immediately after the one driving Creta.
