Re: [algogeeks] puzzle-plz explain stepwise
yx - xy = x0y - yx = (10y + x) - (10x + y) = (100x + y) - (10y + x) 9y - 9x = 99x - 9y 18y = 108x y=6x Since, x comes in hundreds place, we know it can only be 1 as the difference between the 3 digit number and two digit number is difference of two 2 digit numbers only. thus, y=6*1 = 6 a explained earlier avg speed = (106-16)/2 = 45 units -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

After traveling for an hour the driver sees another milestone with the same digits in reverse order.After another hour the driver sees another milestone containing the same two digits.

Re: [algogeeks] puzzle-plz explain stepwise
Relation comes out as : y=6x so x=1 ans y=6. so 1st: 16 (say km) 2nd: 61 3rd: 106 av. speed=(106-16)/2=45 km/hr On Thu, Jul 14, 2011 at 1:13 AM, Siddharth kumar siddhartha.baran...@gmail.com wrote: 1st: xy 2nd: yx 3rd: x0y -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.
