A man is walking towards a vertical pillar in a straight path, at a uniform speed. At a certain point A on the path, he observes that the angle of elevation of the top of the pillar is `30^0` . After walking for 10 minutes from A in the same direction, at a point B, he observes that the angle of elevation of the top of the pillar is`60^0` . Then the time taken (in minutes) by him, from B to reach the pillar, is : (1) 6 (2) 10 (3) 20 (4) 5

A man is walking towards a vertical pillar in a straight path at a uniform speed. At a certain point A on the path, he observes that the angle of elevationof the top of the pillar is 30^(@) . After walking for 5(sqrt3+1) minutes from A in the same direction, at a point B, he observes that the angle of elevation of the top of the pillar is 45^(@) . Then the time taken (in minutes) by him, to reach from B to the pillar, is (take sqrt3=1.73 )
