• distance by taai say X
  by train = 450-x
  taai+train=8130
  15*X+(450-X)*21=8130
  i.e X=220
  train=450-220=230km

• 15x+21y=8130 ----(1)
  
  x+ y=450------------(2)
  
  solving eq (1) & (2),
  
  we get ,x=220 & y=230

• let distance travelled by taai=x
  cost of 1km by taai=Rs. 15
  total cost of distance travelled by taai=15x
  Distance travelled by train=450-x
  cost of 1 km by train=Rs. 21
  total cost by train=21(450-x)
  now
  15x+21(450-x)=8130
  .
  .
  .
  x=220
  journey travelled by train=450-220=230km

• 230 km traveled by train (230*21=4830)
  220 km traveled by taxi (220*15=3300)
  4830+3300=8130.
  which is the total amount paid.
  so journey traveled by train is 230 km.
