If taxi fare is equal to 15rs/km & Train fare is equal to 21rs/km. Total distance traveled is equal to 450 km, total amount charged is equal to 8320 Rs. Then distance traveled by train is ?

• ANS IS:261.66666
  X=TAXI
  Y=TRAIN
  X+Y=450-----------1
  15X+21Y=8320------2
  SOLVING THIS EQUATION WE CAN GET
  Y=261.66666

• Let the total distance travelled by taxi be x.
  then the total distance travelled by train is 450-x
  
  Taxi fare =15rs/km and Train fare= 21rs/km
  
  Then the equation is:-
  
  15X+21(450-X)=8320
  
  X=1130/6
  
  DISTANCE TRAVELLED BY TRAIN = 450-(1130/6)=261.6

• let x be the distance traveled by taxi
  y=distance traveled by train
  then total fare charge= 15x+21y=8320
  total distance traveled= x+y=450
  solving these two equation we get
  y=291.67km

• x+y=450
  15x+21*y=8320
  solving y=261.66

• 15X+21(450-X)=8320
  X=1130/6
  DISTANCE TRAVELLED BY TRAIN = 450-(1130/6)=261.6

• x+y=450
  15x+21y=8320
  solving,y=261.66
• 10 years agoHelpfull: Yes(0) No(0)
• x+y=450
  15x+21y=8320
  hence y will be 261.66

• This is * marked question in TCS paper but their ANS of this question is 291.67km
  but solving the equation
  X+Y=450 ----------1
  15X + 21Y = 8320 ----------------2
  BY these equation y=261.66 km
  this is not in option
  
  Any can explaion that how we find ans 291.67KM

• Vijay, I think that this might be a dummy question.

• for 1 km=rs 21
  2 km=rs 2*21=rs 42
  x*21=rs 8320=>8320/21
  appx=391km
