Answer 1

Answer:

Step-by-step explanation:

The only possibilities are 1+8 2+7 3+6 4+5 5+4 6+3 7+2 8+1 9+0 so we will check and start my the middle so the difference b/w 45 and 54 is 9then difference b/w 36 and 63 is 27 so 3 and 6 are the no..

Answer 2

Answer:

let two digit number is 10x+y

as per question x+y=9 .......eq (1)

question says that 10y+x=27+10x+y

so 9x-9y= -27 .......eq(2)

solving two equations we have x=3 and y=6

so two digit number is 36
