Question

The sum of the digits of a two-digit number is 12. The number obtained by

interchanging the digit exceeds the original number by 54. Find the original number.​

Answer 1

Answer:

Step-by-step explanation:according to the condition,

x+y = 12 or x= (12-y)

now the digit in unit place is x and tens place is y

therefore the no is (10y+x)

by the condition

10y+x = 10x+y+54

or 9x - 9y +54 =0

or 9(x - y + 6) =0

or 12-y - y+6 =0

or -2y +18 =0

or 2y=18

or y=9

therefore x= 12 -y

= 12-9= 3

therefore the original no is 10x +y =10*3+9=39
