Question

In a two digit number the unit's digit is x and the ten's digit is y. Then, the number is​

Answer 1

Answer:

Correct option is

A

10y+x

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+remain

So xy=1×y+x

Answer 2

Answer:

Suppose our number is 83 .It has three at unit digits and 8 at tens digit

So 83 can be written as 10×8+3

Similarly any two digit number say "yx" with x at unit digit and y at tens digitswhich can be written as 10x+y

So we know that

Dividend =divisor ×quotient +remainder

So xy= 10×y+x .
