It’s a 4 digit number. The tens are double the ones. The thousands are double the tens. The sum of the digit is 19

Zielflug [23.3K]

The tens are double the ones: c= 2d
the thousands are double the tens:
a = 2c = 4d
the sum of the digits is 19:: a+b+c+ d = 19

Substitute for a and c to get:
4d + b + 2d + d = 19
b + 7d = 19
d=2;b=5;0=4;a=8
