### Explanatory Answer

##### Method of solving this CAT Question from Ratio, Mixtures and Averages: Given a set of numbers, mean of the overall set, and median of a subset, how does one find the possible range of the median of the overall set.

Let a, b, c, d, e, f be the six numbers in ascending order.
e = 43; a + b + c + d + e + f = 198
Median of 6 integers = $$frac{c + d}{2}\\$ $\frac{c + d}{2}\\$ is maximum when c and d are maximum since e = 43, dmax = 42 and cmax = 41 $\frac{c + d}{2}\\$ is minimum when c and d are minimum amin = 1, bmin = 2, cmin = 3, dmin = 4 Therefore, = $\frac{c + d}{2}\\$min = 3.5 Max – min = 41.5 – 3.5 = 38 The question is "What is the difference between the highest and lowest possible median of the 6 numbers?" ##### Hence, the answer is "Highest and lowest possible median is 38". ###### Fabulous 5,000 off on CAT Online Courses.
