Answer 1

Step-by-step explanation:

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

▪️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
