Question

It’s Valentine’s Day and five boys Amit, Bhuvan, Chetan, Dilip and Ehsaan are buying flowers for their respective girlfriends. Each of these boys has a preference from 1 to 5 (1 being first preference, it is given the first rank) of flowers among orchid, rose, carnation, gerbera and daffodil. There is a level of dissimilarity between the five boys and this is measured as the sum of the differences in the ranks assigned by them to each of these 5 flowers. The greater this difference, the more dissimilar the persons.
The following table indicates the preferences of each of these five boys:
$\begin{array}{cccccc}& \text{AMIT}& \text{BHUVAN}& \text{CHETAN}& \text{DILIP}& \text{EHSAAN}\\ \text{ORCHID}& \text{2}& \text{5}& \text{1}& \text{4}& \text{1}\\ \text{ROSE}& \text{4}& \text{2}& \text{3}& \text{3}& \text{3}\\ \text{CARNATION}& \text{3}& \text{1}& \text{4}& \text{2}& \text{2}\\ \text{GERBERA}& \text{5}& \text{4}& \text{5}& \text{1}& \text{4}\\ \text{DAFFODIL}& \text{1}& \text{3}& \text{2}& \text{5}& \text{5}\end{array}$
