Raj travels a part of jouurney by taxi paying 15 per km and rest by train paying 21 per km if he travels a total of 450 km and pay 8130 then distance traveled by raj in train

• ans=230
  let x=distance travelled by taxi
  y=by train
  15x+21y=8130
  x+y=450
  by solving this two eqn we get ans..

• let x by taxi y by train
  then 15x+21y=8130 and x+y=450
  after solving them we get y=230 ans.

• let ,raj travels by taxi x km
  & travels by train y km
  x+y=450-----(i)
  15x+31y=8130-----------(ii)
  solving these two equation
  we get x=220km(travels by taxi)
  y=230km(travels by train)

• Ans : 230
  
  let Raj travels x km by taxi .
  Total distance travelled by him = 450
  Thus , remaining distance = (450- x ) is travelled by train..
  By taxi , he pays Rs 15 per km . Thus , for x km, he pays = Rs. 15*x
  For (450- x) km , he pays = 21*(450-x)
  Total amt he paid = 8130
  8130=15*x + 21(450-x)
  by solving the above equation , x= 220
  450- 220=230 km is travelled by train.

• let x be the distance covered by taxi and 450-x covered by train
  15x+21(450-x)=8130
  x=220
  so distance covered by train=450-220=230

• 15*B+21*T=8130
  B+T=450
  
  by solving we get T=230

• let distance travelled by train= x
  ..................................... taxi= 450-x
  15*(450-x)+21x=8130
  x=230
