Question

sum of the digit of a two digit number is 9. when we interchange the digits, it is found that the resulting new number is greater than the original number by 27. what is the two digit number?​

Answer 1

Answer:

Let d no. be 10x+y

I condition

x+y=9

=>y=9-x.........1

II condition

10y+x=10x+y+27

9y-9x=27

y-x=3

9-x-x=3 (from 1)

-2x=-6

x=3

Subs x in 1

y=9-3

y=6

Therefore the no. Is 36
