1. Answer:

   Suppose our number is 53.It has 3 at units digit and 5 as tens digit

   So 53 can be written as 10×5+3

   Similarlly any 2 digit number say ‘yx’ with x at units digit and y as tens digit which can be written as 10x+y

   Another approach is say our number is yx then by dividing it with 10 we get remainder x and quotient as y

   So we know that dividend=divisor×quotient+remainder

   So xy=10×y+x
