I tryin to figure out how to crack DS/PS questions where Median or mean is mentioned for a given set of #s and one is suppose to find the one or the other .
For xample ,i ran into this DS Q
M is odd integer , what is the arthmetic mean of a set with m integers ??
1. integers in set are consecutive # ,multiple of 3
2. Median of set of integers is 33 -
I suppose median here indicates middle # , ie the set will hv exactly the same # of elements after this point .
But how can one reach to sure conclusion the set indeed has Odd # of elements (as in this case apparently) ??
R there any rules around concluding the # of elements in the set based on type of elements(even/odd) and median given ??
help is appreciated
