An organization conducted bike race under 2 different categories–boys and girls. Totally there were 250 participants. Among all of them finally three from Category 1 and two from Category 2 were selected for the final race. Ravi forms two sets B and G with these participants for his college project.
Let B = {b_{1}, b_{2}, b_{3}} G = {g_{1}, g_{2}} where B represents the set of boys selected and G the set of girls who were selected for the final race.
Ravi decides to explore these sets for various types of relations and functions
Ravi wishes to form all the relations possible from B to G. How many such relations are possible?

Students of Grade 9, planned to plant saplings along straight lines, parallel to each other to one side of the playground ensuring that they had enough play area. Let us assume that they planted one of the rows of the saplings along the line y = x − 4. Let L be the set of all lines which are parallel on the ground and R be a relation on L.
Let relation R be defined by R = {(L_{1}, L_{2}) : L_{1}  L_{2 }where L_{1,} L_{2} ∈ L} then R is______ relation
