There ARE SOME COINS IN THE BAG(1 Ps,5 Ps,10 Ps,25 Ps).A person HAS TO DISTRIBUTE COINS TO TS IN SUCH A WAY THAT EACH ONE GET 50 PAISE exact HAVING NO 2 GETTING THE SAME DENOMINATION OF COINS.THEN HOW MANY CHILDRENS ARE THERE ??? Sharmila has to write an analysis on the cost and speed of 5 cars (A, B, C, D and E) and 3 motorcycles ( P, Q and R). A is
the fastest among the cars and R is the slowest among the motorcycles. C is costlier than D and Q but cheaper than B.
Among the cars, A is not the costliest. D is cheaper than E and there is no car whose cost lies between the cost of these
two. E is faster than three of the cars and all the motorcycles. Q is costlier than R but cheaper than P, which is faster
than Q. Now, based on her analysis, Professor Venkat asks her to verify the following statements and determine which
statement must necessarily be true.
OPTIONS
1) D can be the median value among cars as far as their cost is concerned.
2) If P is costlier than E, exactly 2 cars are cheaper than P.
3) If P is cheaper than A which is not costlier than E, R is the cheapest of all cars and motorcycles put
together.
4) None of the above
