A train travelling with constant speed crosses a 96 m long platform in 12 sec and another 141 m long platform in 15 sec .The length of the train and its speed are?

• Length=84 m, Speed=15 m/s
  
  Let the length of the train be x m and speed be y, then
  96+x = 12y ---(i) and 141+x = 15y ---(ii)
  Solving (i) & (ii), we get x=84, y=15
