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.
