The difference between a two digit number and the number obtained by interchanging its digits is 63 . What is the difference between the digits of the number ?

Let the digit in the * units place* of the number be

*x*and the number in the * tens place* be

*y.*Then the **numbe**** r** = 10*y +x =

**10y + x**On * reversing* the digits,

the number obtained = __10x + y__

BTP,

**(10y + x) - (10x + y) = 63**

=> **10y + x - 10x - y = 63**

=>** x - y = 63**

Therefore,

the * difference between the two digits* =

*=*

**x- y**

**63****A n s . ) 63**

Hope it helps!!!
