Step-by-step explanation:

let four digit number be abcd

here

a=2d

c=1+b

a+b+c+d=13

2d+b+1+b+d=13

3d+2b=12

if d=0(not satisfied)

d=1(not satisfied)

d=2(satisfied)

d=4(satisfied)

case 1

if d=2 then b=6

c=7 and a=4

number is 4672

case 2:-

if d=4 then b=0

c=1 and a=8

number is 8014

number 8014 only satisfies as it's sum is 13 where as 4672 doesn't satisfy as it sum is 19
