If the tens digit x and the units digit y of a positive integer n are reversed, the resulting integer is 54 more than n. What is y in terms of x ?
Choose the correct choice from the following options:  A) x-10  B) x-12  C) x+8  D) x+6  E) x+7
Original Digits=xy i.e. Number=10x+y   After reversing the digits:   Digits=yx i.e. Number=10y+x   10y+x is 54 more than 10x+y   10x+y+54=10y+x   10x-x+54=10y-y   9x+54=9y   x+6=y   OR   y=x+6   Answer : x+6
