Question

find the smallest 2 digit number that is 36 more than the number with it's digits reversed

Answer 1

Answer:

40

Step-by-step explanation:

let the number is 10y + x

unit place = x

tenth place = y

given, 10y + x = 10x + y + 36

=> 9y - 9x = 36

=> y - x = 4

=> y = x + 4

if x = 0 then y = 4

this is smallest. because both x and y are individually non negative

Answer 2

Answer:

40 is the correct answer
