Answer 1

Answer:

let the hundreds digit be x

---------tens digit be  y

---------units digit be z

x=4z

=> 4z+y+z=14

=> 5z+y=14

so the number is 100x+10y+z

                         =  400z+10y+z

                          =  401z+10y

now reversed  is 100z+10y+4z

                          = 104z+10y

they differ by 594

401z+10y-104z-10y=594

297z=594

z=2

so 5z+y=14

    y=14-10

    y=4

x=4*2=8

so the number is 842
