If the tens digit x and the units digit y of a positive integer n are reversed, the resulting integer is 36 more than n. What is y in terms of x ?	Pick: A) x-2 B) x-4 C) x+4 D) x-3 E) x-1
Original Digits=xy i.e. Number=10x+y   After reversing the digits:   Digits=yx i.e. Number=10y+x   10y+x is 36 more than 10x+y   10x+y+36=10y+x   10x-x+36=10y-y   9x+36=9y   x+4=y   OR   y=x+4   Answer : x+4
