The 4 digit number is 1349.
It is given that the first digit is 1/3 of the second. There
are 3 such possibilities.
1. 1 and 3
2. 2 and 6
3. 3 and 9
Now, the third digit is the sum of the first and second digits.
1. 1 + 3 = 4
2. 2 + 6 = 8
3. 3 + 9 = 12
It is clear that option 3 is not possible. So we are left
with only two options. Also, the last digit is three times
the second, which rules out the second option. Hence, the
answer is 1349.

Answer / nessa
first=f,second=s,third=T,Last=L
f=s/3
T=f+s
L=3s
since s is divisible by 3,so s can be 3,6,9
Taking s=3
f=1
T=3+1=4
L=3*3=9
so answer is 1349

He then used up six of the matches, and found that with the remainder he could again construct another triangle whose area was just as many square inches as there were matches. And using another six matches he could again do precisely the same. How many matches were there in the box originally? Note that the match-box can hold maximum of 50 matches.
