. The number of points having both co
ordinates as integers, that lie in the interior of the triangles with vertices (0, 0), (0, 41) and (41, 0) is
A: 901
B: 861
C: 820
D: 780
Best Answer
Explanation:
Required point (x,y) is such that it satisfies
X+y<41&x>0andy>0
Number of positive integral solutions of the equation x+y+k=41 will be the number of integral coordinates in the bounder region.
Therefore, the total number of integral coordinates,
Final Answer:
Hence,option (D) is correct. i .e 780
