Akanksha Mishra  (10 years ago)

We know:
prime digits= 2,3,5,7

According to question;

fifth is half of the fourth
so 5th can be 1,2,4 &
4th can be 2,4,8

sum of 4-th and 5-th digit is less
that first so can be
(1+2) not possible as 5th=1
but 2nd is lowest
(2+4) or
4+8=12 not possible as less than 1st
so 5th digit=2, 4th digit = 4---42

1st can be 7,8,9 but 3rd is highest
so 1st can be 7,8 1st digit is 1 less that 3rd digit so
1st digit=7,
3rd digit=8
7_842
2nd is lowest so 2nd digit= 1 (as 2 is already present)

So answer will be 71842

prime digits= 2,3,5,7
fifth is half of the fourth so 5th can be 1,2,4 & 4th can be 2,4,8
sum of 4-th and 5-th digit is less that first so can be
(1+2) not possible as 5th=1 but 2nd is lowest
(2+4) or 4+8=12 not possible as less than 1st
so 5th digit=2, 4th digit=4 ---42
1st can be 7,8,9 but 3rd is highest
so 1st can be 7,8 1st digit is 1 less that 3rd digit so
1st digit=7, 3rd digit=8
7_842
2nd is lowest so 2nd digit= 1 (as 2 is already present)
so no. is 71842
