Consider a triangle drawn on the X-Y plane with its three vertices at (41, 0), (0, 41) and (0, 0), each vertex being represented by its (X, Y) coordinates. The number of points with integer coordinates inside the triangle (excluding all the points on the boundary) is
Correct Answer : A
In the X-Y plane, the area of the region bounded by the graph of |x + y| + |x – y| = 4 is
Which of the following lines does not pass through the point of intersection of the two lines 2lx + 3my+n= 0 and 3lx - 4my-n = O?
Four points A, B, C and D lie on a straight line in the X-Y plane, such that AB = BC = CD, and the length of AB is 1 metre. An ant at A wants to reach a sugar particle at D. But there are insect repellents kept at points B and C. The ant would not go within one metre of any insect repellent. The minimum distance in metres the ant must traverse to reach the sugar particle is
