    Answer:

    Step-by-step explanation:

    Let the number be x

    So

    First its ten’s digit is 4 times the units place

    [4×10+1]X=41x

    or the other combination

    (8×10+2)X=82x

    82-54=28 is the reverse of number…

    So 82 is that number…

    Its logical approach…not acutal one

    AND

    let the two digit no be 10x + y

    according to the question:

    4x = y

    also,

    (10x + y ) – 54 = 10y + x

    on solving this

    9x – 9y = 54

    taking 9 common:

    9( x-y) = 54

    substituting 4x = y

    x-4x= 6

    -3x = 6

    x= -2

    y = 8

    so the no is 28 or -28

    Hope it will help you out
