Question

a two digit no. whose one's digit is n and ten's digit is y is?​

Answer 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 yxthen 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

tens = y =10y

ones =n
