2[x]^2 = [x] + 1.
this equation uses [x] which is greatest integer greater than equal to x.
can someone please explain the approach,
two trains start simultaneoulsy from P and Q towards Q and P resp. at 8 am. They cross each other at 12 noon. Train starting from Q thereafter takes 6 hrs to reach P. On a particular day the train starting from P reduced its speed and arrived at Q 200 mins late. At what time did the trains cross each other on that day.

A box contains 6 books on Mathematics, 8 books on Economics, 5 books on History, 4 books on Philosophy and 7 books on Politics. What is the minimum number of books one should take out of the box to ensure that at least one book on each of the five subjects has been picked up?
The OA is 27 but shouldn't that be the case when maximum number of books are taken out..IMO for minimum it should be 5..each of a subject...
can anyone tell where am i wrong...

Two cars P and Q start from two points A and B towards each other simultaneously. They meet for the first time In 40km from B. After meeting they exchange their speed as well as directions and proceeded to their respective starting points, they turn back with the same speeds and meet at a point 20km from A. What is distance between A and B?
If 2 unbiased dice are cast simultaneously, which number has the highest probability of turning up as the sum of the numbers on the dice ??

How long did Mr. X take to cover 5000 km journey with 10 stopovers?
I. The ith stopover lasted i^2 minutes.
II. The average speed between any two stopovers was 66 kmph.
(a), if the question can be answered with the help of statement I alone,
(b), if the question can be answered with the help of statement II alone,
(c), if both, statement I and statement II are needed to answer the question
(d), if the statement cannot be answered even with the help of both the statements.
Two vessels, A and B, contain milk and water respectively. The volume of milk in A and the volume of water in B are in the ratio 4 : 5. Now, x litres of milk from A is poured into B and then y litres of the solution from B is poured into A. If as a result, the concentration of milk in A and that of water in B, both dropped from 100% to 200/3%, find x : y.
PLEASE EXPLAIN THE APPROACH.
