aj travels a part of his journey by taxi paying Rs15 per km and the rest by train paying Rs21 per km if he travels total 450km and pays Rs8130 the distance travelled by rail is a)180km b)260km c)190 d)230

• Let distance travelled by taxi be x and by train by y.
  x+y=450............................(i)
  15x+21y=8130.....................(ii)
  solving (i)&(ii)
  y=230

• let the distance traveled by train be x
  distance travel by taxi = 450 - x
  as per the ques
  21*x + 15*(450 - x) = 8130
  => x = 230.
  distance traveled by train = 230 km.

• let distance travel by taxi is x km and distance travel by rail is y km
  here given x + y =450 km---eq1
  15 x +21 y =8130 -----eq2
  from eq1 and eq2 we get x =220 km and y =230 km
  ans is y =230 km

• Let distance travelled by taxi=x km
  Then distance travelled by train=450-x km
  total money paid is Rs8130
  So,
  15x+(450-x)21=8130
  x=220
  So, distance travelled by taxi is 220
  Distance travelled by train is 450-220=230

• d) 230
  15x+21y=8310
  x+y=450
  solving for y, y=230
