82

Step-by-step explanation:

Let the number be xy

Ten's digit: x

One's digit: y

    Tens digit = 4 * ones digit

                   x = 4y => (i)

Sum of digits = 10

             x + y = 10

           4y + y = 10  => from (i)

                 5y = 10

                   y = 2

                   x = 4*2 = 8  => from (i)

Hope this helps :)
