If the tens digit x and the units digit y of a positive integer n are reversed, the resulting integer is 27 less than n. What is y in terms of x ?	Choose the correct choice from the following:
A) 10 - x
B) 9 - x
C) x + 3
D) x - 3
E) x - 9
Original Digits=xy i.e. Number=10x+y   After reversing the digits:   Digits=yx i.e. Number=10y+x   10y+x is 27 less than 10x+y   10x+y-27=10y+x   10x-x-27=10y-y   9x-27=9y   x-3=y   OR   y=x-3   Ans:x - 3
