If the tens digit x and the units digit y of a positive integer n are reversed, the resulting integer is 45 more than n. What is y in terms of x ?	Choose the correct answer:  A) x+5  B) x+3  C) x+4  D) x-3  E) x-4
Original Digits=xy i.e. Number=10x+y   After reversing the digits:   Digits=yx i.e. Number=10y+x   10y+x is 45 more than 10x+y   10x+y+45=10y+x   10x-x+45=10y-y   9x+45=9y   x+5=y   OR   y=x+5   x+5nswer : x+5
