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.
