Question

the sum of the digit of a two digit number is 12 if the number formed by reversing the digit is greater than the orignal number by 54 find the orignal number

Answer 1

let unit digit be x and tens digit be y
so according to question

x+y=12. (i)

suppose no. was 10y+x
so after reversing it will become 10y+x

now according to condition

10y+x=10x+y+54

now solve these two equations.....

9y-9x=54

y-x=6. -(ii)

y=9
and. x=3

Answer 2

the number/answer for the question given above is 39. As the sum of the two digits (3,9) is 12, the number when reversed gives 54 as difference between the original number (93),(93-39=54).
