Raj and Atul start running towards each other simultaneously from the opposite ends of a linear racing track and take 81 seconds and 100 seconds respectively to reach the other end after crossing each other. If Raj and Siraj also start running towards each other simultaneously from opposite ends of the same track such that Raj takes 114 seconds to reach the other end after they cross each other, then how much time will Siraj take to run the entire length of the racing track?
