Question

a + b + c = 9,
2 < a < 6,
1 < b < 6,
2 < c < 8
Possible number of solutions is

Answer 1

a = 3
2 < 3 < 6

b=3
1 < 3 < 6

c=3
1 < 3 < 8
hence... a = b = c = 3

Answer 2

Possible values of a are 3 4 5
b—-> 2 3 4 5
c——> 3 4 5 6 7

Possible values for (a,b,c) are
(3,2,4),(3,3,3),(4,2,3)

So possible number of solutions is 3
