Question

A number of three digits has the hundred digit 4 times the unit digit and the sum of the three digits is 14. if the three digit are written in the reverse order, the value of the number is decreased by 594.find the number.

Answer 1

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
