a) Bablu: 1, Ramesh: 0
A triangle can only be true if the sum of two sides are bigger than the other side.
Bablu- 3+4=7>5
5+4=9>3
5+3=8>4
Therefore it can be a proper triangle. But we can only make one triangle out of it .
Ramesh- 3+5=8<9
Therefore it is not a proper triangle we cannot even make one triangle out of it so 0.
I hope it helps.
