a person has to select one of the 3 capsules , 1st increase his wt by 1 kg. another ensures that the wt does not change. the third one increase his wt by 2 kg and also compels him to choose one of the 3 capsules again-all similar to the first set of three capsules. The person has no way of identifying the capsules beforehand and equally likely to take any of the 3 capsules at any stage. Find the expected gain in the wt.

(CAT 2005)A jogging park has two identical circular tracks touching each other, and a rectangular track enclosing the two circles. The edges of the rectangles are tangential to the circles. Two friends, A and B, start jogging simultaneously from the point where one of the circular tracks touches the smaller side of the rectangular track. A jogs along the rectangular track, while B jogs along the two circular tracks in a figure of eight. Approximately, how much faster than A does B have to run, so that they take the same time to return to their starting point?
