Answer 1

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

(8x10+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
