A line x + y = 14 cuts the curve y = x2 + 4x at two distinct points. What type of triangle will be formed by joining these two points to a third point (1, 20)?
if abc = 1, then sigma [(1 + a + b^-1)] = ??
If a^3 = b^3 =c^3 = 1 and a, b and c are distinct values, then a+b+c=?

There are eight friends: four boys and four girls. Sheldon, Leonard, Raj and Howard are the boys and Penny, Bernadette, Amy and Leslie are the girls. All of them are sitting around a rectangular table having eight different chairs (chairs cannot be moved) such that there are three seats along each longer side and one seat each on the shorter sides. Sheldon, being the leader, likes to sit on the shorter side of the table. Raj does not talk to girls, so he does not sit next to any of the girls. Leslie wants to sit opposite Sheldon. Friends whose names start with the same letter do not sit adjacent to each other. In how many ways can these eight friends be arranged, if they face each other?

Three boys A, B and C start running at constant speeds from the same point P along the circumference of a circular track. The speeds of A, B and C are in the ratio 5:1:1. A and B run clockwise while C runs in the anticlockwise direction. Each time A meets B or C on the track he gives them a card.

3 pipes are connected to an inverted cone, with its base at the top. 2 inlet pipes, A and B, are connected to the top of the cone and can fill the empty cone individually in 8hrs and 12hrs hours, respectively. The outlet pipe C, connected to the bottom,can empty a filled cone in 4 hours. When the cone is completely filled with water, all three pipes are opened. Two of the three pipes remain open for 20 hours continuously and the third pipe remains open for a lesser time. As a result, the height of the water inside the cone comes down to 50%. Which of the following would be possible?
A. Pipe A was open for 19 hrs.
B. Pipe A was open for 19.5 hrs.
C. Pipe B was open for 19 .5hrs.
D. Pipe C was open for 19 hrs 50 min.
E. The situation is not possible.
