A number of three digits has the hundred digit 4 times the unit digit and the sum of the digits is 14. l the three digits are written in the reverse ander the value of the number is decreased by 54. Find the number​

Answer 1

Answer: hey there, number is 842

Step-by-step explanation:

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

hope it helps you !!!
