An equilateral triangle ABC has area 3 sq. cm. Now a second equilateral triangle is formed inside it by joining the mid-points of its sides. Then another equilateral triangle is formed by joining mid-points of this 2nd equilateral triangle's sides. This process continues on till infinity. WHat will the sum of area of all such equilateral triangles ??
A policeman takes 10 steps to reach the bottom of the running escalator (ie. in same direction downward as the direction of escalator). As he reached the bottom, he hears 'chor chor' and run backs upward on the same escalator 10 times faster, on the way he takes 25 steps to reach just the top of the escalator moving in downward direction. How many steps on his way upwards are visible to us ? (22, 20, 18, 17)
