Two classrooms A and B having capacity of 25 and \( (n-25) \) seats respectively. \( A_{n} \) denotes the number of possible seating arrangements of room A, when n students are to be seated in these rooms, starting from room A which is to be filled up full to its capacity. If \( A_{n}-A_{n-1}=25 \) ! \( \left({ }^{49} C_{25}\right) \) then n equals -https://bit.ly/YTAI_PWAP https://www.pw.live
