an employee may claim rs 7.00 for each km when he travels by taxi and rs 6.00 for each km if he drives his own car .if in one week he claimed rs 595 for travelling km.how many kms did he travel by taxi ?

• this question have so many solutions....
  because you didn't mention min or max...rs...for the week...
  595/7 = 85...so answer should be 85...
  other solutions are...
  let me tell one thing 7 and 6 are co-prime...so 7*6 =42...
  every time reduce 42 from 595 and get new solution up to >=0...
  for example...
  595-42 = 553 .... 553/7 =79 by taxi and 42/6 = 7 by own car...
  553-42 = 511 .... 511/7 =73 by taxi and 84/6 = 14 by own car....
  like that....

• travel by taxi =x km
  drives his own car=y km
  now according to question
  7x+6y=595------------(1)
  no other condition given so we can set any value of x and get y
  ex-x=85 and y=0
  x=79 and y=7
  x=73 and y=14
  x=67 and y =21
  x=61 and y=28
  x=55 and y=35.....
  so it hv many solution...

• Let x and y be the respective km's travelled by man via taxi and by his own car.
  Given x + y = 90 => x = 90 - y
  But according to the question,
  7x + 6y = 595
  7(90-y) + 6y = 595
  => 630 - 7y + 6y = 595
  => y = 630 - 595 = 35
  => x = 90 - 35 = 55
  Therefore, the distance travelled by taxi is 55 kms.
