Question

Sum of the digits of a two-digit numb
is 5. When we interchange the digits,
found that the resulting new number
less than the original number by 27.
What is the two-digit number?​

Answer 1

Step-by-step explanation:

let the digit at one's place be y and at tens place be x

no.=10x+y

x+y=5

y=5-x

according to the statement

10x+y-27=10y+x

10x+5-x-27=10(5-x)+x

9x-22=50-9x

18x=72

x=4

y=5-x

y=1

no. is 10x+y

=41
