Question

the difference between a 2 digit no. And the number obtained by reverseing the digits is 54 find the difference between digit of 2 digit number

Answer 1

let the 2 digit number is 10x+y

ATQ,

10x + y - 10y - x = 54

9x - 9y = 54

9(x-y) = 54

x-y = 54/9

x-y = 6

so the difference between the 2 digits of the number is 6
