From any point inside equilateral triangle,the lengths of perpendiculars on the sides are a cm b cm and c cm. Its area is
1)(a+b+c)/root3
2)root2/3 * (a+b+c)^2
3)root2/3 * (a+b+c)
4)(a+b+c)^2/root3
if a b c are real and a^2+b^2+c^2=2(a-b-c)-3 then a+b+c is equal to ?
(a^2-bc)/(a^2+bc) + (b^2-ca)/(b^2 + ca) + (c^2-ab)/(c^2+ab) =1
then the value of
a^2/(a^2+bc) + b^2/(b^2 + ca) + c^2/(c^2+ab)=?
The total numbers below 1000 whose sum of digits as 12 ?

Rahul and Naren play a peculiar game with marbles. The marbles are first arranged in four piles, each of 35, 36, 37 and 38 marbles respectively. At each turn, a player chooses one of the piles available and divides it into smaller piles, both of which are then included in the piles available for the next player, and so on. The loser is the player who cannot do this. Assume that they play intelligently and they play to win.
Which of the following statement is/are false?
I. Rahul can never win if he were to start the game.
II. Rahul will win everytime he starts the game.
III. Rahul can win irrespective of who starts the game.
IV. Naren can never win, if he does not start the game.
a. Only I, II and III
b.Only IV
c.Only I
d. Only II, III and IV
A cylindrical vessel of diameter 24 cm contains some water.If two spheres of radii 6cm each are lowered into the water until they are completely immersed ,then the water level in the vessel will rise by??
(a+b-c)/(a+b)=(b+c-a)/(b+c)=(c+a-b)/(c+a) and a+b+c not equal to 0 then
a)a is equal to b is not equal to c
b)a is not equal to b is equal to c
c)a is not equal to b is not equal to c
d)a is equal to b is equal to c
