Answer 1

Answer:

26

Step-by-step explanation:

let x be the tens digit . then unit digit = 3x

then the original no.= 10(tens digit )+ unit digit

                                 = 10(x) + 3x

                                 = 13x

the reversed no. = 10(tens digit )+ unit digit

                            = 10(3x) + x

                            = 31x

reversed no. - original no. = 36

31x - 13x = 36

18x = 36

x = 2

original no. = 13x

                   = 13 * 2

                   = 26
