Question

6.
(a) 10y + x (b) 10x + y (C) 10xy (d) y + x
If the line y = px -2 passes through the point (2, 2), then the value of P 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+remainder

So xy=10×y+x
