Answer 1

Here is the solution for number 5

Answer 2

Given:

Product of digits = 18

when 63 is subtracted from no. digits get interchanged

To Find:

The number

Solution:

Let the no. be (10x+y)

•°•From first condition we get,

$x \times y = 18$

from second condition we get,

$(10x + y) - 63 = (10y + x)$

$10x + y - 63 = 10y + x \\ 9x - 9y = 63 \\ 9(x - y) = 63 \\ x - y = \frac{63}{9} = 7 \\ x - y = 7$

Now,by putting first condition in second by substitution method

we will get 2 values of -9 or 2 but -9 is invalid so y=2........(Refer to attachment )

x = \frac{18}{2} = 9[/tex]

so the no. will be 29

Hope this helps you
