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 explai
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

For more op
initially he saw say "xy" then he saw "yx" now what next does he
see...containing only x and y??
Please clarify your question..
