Step-by-step explanation:

Let the no at unit place be x and at tens place be y

therefore no =10y +x

acc to first con

x+y=9. .......(1)

second cond

10y+x-27=10x +y

10y-y =10x-x+27

9y=9x +27 divide by 9

y=x+3

y-x=3......(2)

adding (1) and (2) we get

2y =12

hence y =6

substitute it in 1

x+y =9

x+6=9

hence x=3

the no =10y + x

=10 X 6 + 3

=63
