Answer: 7241
Explanation:
If the number is abcd,
then as per puzzle,
b=c/2, c=a-3, a=6+d,
so 'd' < 4 since a cannot be greater than 9.
'd' has to odd, since 'b' = (d+3)/2
only values left for 'd' are 1 and 3.
Also, 'd' cannot be 3 since that will result 'c' as 3 which
is not allowed (no repitition).
Hence 'd' is 1.
Thus resulting number is 7241.

Answer / mahesh
hai guys , first
The second digit number is half less than the third one
so the possiblities are
-12- (or) -24- (or) -36- (or) -48-
(i) if i take
-12-
then the 3rd digist should be 3 less than first one , it is
not possible
(ii)
if i take
-24-
then the 3rd digist should be 3 less than first one , it is
possible to place 7 at the first place
So
724-
Then the first digit is 6 more than the 4 digit
