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

8. Given a collection of points P in the plane , a 1-set is a point in P that can be separated from the rest by a line, .i.e the point lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P). The minimum value of n1(P) over all configurations P of 5 points in the plane in general position (.i.e no three points in P lie on a line) is a) 3 b) 5 c) 2
