Re: [algogeeks] an amazing amazon question!
+1 sagar pareek... i used the following approach: let the num be xy so... (10y + x) - (10x + y) is the distance travelled in 1 hr... now, the the next milestone must be a three digit number, which can be of following compostion: 1xy or xzy or yzx whr 0=z9 coz aif z=9, distance travlled in tht hr wud be more thn 100, which can nt be the case( in contradiction with the distance in 1st hr)... now if its 1xy, 9(y-x) = 100 + 9 (x-y) which can nt give integral soln..so num must be xzy...thn 9(y-x) = 99x + 10z - 9y... now fr integral solution: z must be a multiple of 9, can be 0 or 9... hence it has to be 0. so 9(y-x)=9(11x-y) 2y=12x y=6x posbl soln: x=0,y=0...rejected x=1, y=6... accepted On Wed, Aug 17, 2011 at 11:22 PM, Rohit Srivastava access2ro...@gmail.comwrote: logic plz?

@sagar. Can you please explain how you got the solution? Is there any proper math involved??
