There are two vessels, P and Q, containing only milk and only water respectively. The volume of milk in P is the same as the volume of water in Q. Now one-third the contents of P are poured into Q, after which one-fourth the contents of Q are poured back into P. If this process is repeated 15 more times, what is the approximate final concentration of milk in vessel P?

Sonal and Deepali started swimming towards each other simultaneously from points A and B respectively situated at two ends of a 96 km long stretch of a river. Destinations of Deepali and Sonal were points A and B respectively. Both of them could swim at 12 kmph in still water. When they started, it was high tide and Sonal swam against the stream. As soon as they met, the tide changed to ‘low tide’ and then Deepali faced the resistance of the stream. Deepali and Sonal took 7 hr 12 min and 8 hr min to reach their destinations respectively. [Speed of the stream during high and low tide need not necessarily be the same.] "
If they had continued to swim back to their respective starting points after reaching their destinations, then where would they have met during the return journey? [Assume tide changed only once, immediately after their first meeting] Source CL
- 32 km from A
- 72 km from A
- 60 km from B

A square ABCD is given with its center as O. Now A and B are joined to O. Balls of three different colors are given and we have to put those balls on A,B,C,D and O such that the colour of the balls on the points which are connected by a line segment is different. In how many ways can we accomplish this task?
Also explain the approach.

Al walks down to the bottom of an escalator that is moving up and he counts 150 steps. His friend, Bob, walks up to the top of the escalator and counts 75 steps. If Al's speed of walking (in steps per unit time) is three times Bob's walking speed, how many steps are visible on the escalator at a given time? (Assume that this value is constant.)
