Answer 2

Answer:

82

Step-by-step explanation:

Let the unit place digit be X

Ten's place digit is(=) 4 times(4×) the unit place digit(X)

Ten's place digit = 4X

According to Question

Ten's Place Digit + Unit Place Digit = 10

                                              4X + X = 10

                                                    5X = 10

                                                      X = 2

Units place digit(X) = 2 and Ten's Place digit (4X) = 8

We know that two digit number is of the form

10(Ten's Place Digit) + Unit Place Digit

         = 10×8 + 2

         = 82

∴Desired Two Digit number is 82
