Answer 1

Answer:

842

Step-by-step explanation:

Suppose number is abc,

1. b=2c

2. a=2b=4c

3. abc/2= ..1

As each of a,b,c are within range of 0-9, max value a can get is 8

Possible values of a=4 or 8, then b=2 or 4, then c=1 or 2

As per 3. above c cant be 1 so it is 2 and therefore b=4 and a=8

The number we get = 842, when divided by 2 we get 421
