Dexter and Prexter are competing with each other in a friendly community competition in a pool of 50 m length and the race is for 1000 m. Dexter crosses 50 m in 2 min and Prexter in 3 min 15 sec.
Each time they meet/cross each other, they do handshake's. How many such handshake's will happen if they start from the same end at the same time?
