Re: [algogeeks] Re: an amazing amazon question!
@Douglas nopes there is only one solution here it is * See answer is in the question ques is saying that first there is 2 digit number after 1 hour number interchanged so let numbers be xy then yx now third it is saying that both numbers are again repeating and we also know that yx>xy and yx-xy <100 so third number must be 1bc where bc may be xy or yx or having any one of x or y when one may be '1' now x*10+y + z = y*10 + x also 1bc = 10*y + x + z 1bc = yx + yx - xy 1bc = 2yx -xy 1bc = 2*(10y+x) - 10x -y 1bc= 20y +2x -10x -y 1bc= 19y - 8x now let number be 1xy = 100 + 10*x +y = 19y - 8x 100 + 18x = 18y 50 + 9x = 9y --> no integer solution now let number be 1yc where x=1 so 100 + 10y + c = 19y - 8 108 + c = 9y --> gives either y>9 or c>9 and it will not satisfy the conditions except the following now let number be where x=1 1cy = 100 +10c + y = 19y - 8 108 +10c = 18y --> gives y=6 and c=0 i hope i explain better :) :) * On Wed, Aug 17, 2011 at 11:51 PM, sagar pareek wrote: > @rajul dave > 45 miles per hour is uniform speed > > > On Wed, Aug 17, 2011 at 11:49 PM, rajul jain wrote: > >> but its speed is uniform i think Don answer is right >> >> >> On Wed, Aug 17, 2011 at 11:42 PM, Douglas Diniz wrote: >> >>> There are infinite solutions with this logic, because the third >>> milestone can have more than 2 digits. >>> >>> On Wed, Aug 17, 2011 at 3:08 PM, sagar pareek >>> wrote: >>> > @rajul >>> > >>> > 61-16 =45 >>> > >>> > its not 55 miles per hour >>> > >>> > On Wed, Aug 17, 2011 at 11:33 PM, Don wrote: >>> >> >>> >> Actually you are all wrong.

There are infinite solutions with this logic, because the third milestone can have more than 2 digits.
