Answer 2

Answer:

let the numbers be in the form

tens. ones

x. y

value is 10x+y

and given x+y = 9

after subtracting 27

tens. ones

y. x

value is 10y+x

=> 10x+y - 27 = 10y+x

=> 9x-9y = 27

=> x-y = 3 ..................(1)

and x+y = 9 ..............(2)

equation (1)+(2) is 2x=12

=> x=6

x+y = 9 => 6+y = 9 => y=3

So, the number is 63

VERIFICATION

63-27 = 36

And 63 reversed to get 36

and 6+3 = 9
