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:

$$\begin{array}{cccccc}& \text{Amit}& \text{Bhuvan}& \text{Chetan}& \text{Dilip}& \text{Ehsaan}\\ \text{Orchid}& 2& 5& 1& 4& 1\\ \text{Rose}& 4& 2& 3& 3& 3\\ \text{Carnation}& 3& 1& 4& 2& 2\\ \text{Gerbera}& 5& 4& 5& 1& 4\\ \text{Daffodil}& 1& 3& 2& 5& 5\end{array}$$

Q. The pair of persons who are the most dissimilar among the following is:

• A. Amit- Bhuvan
• B. Bhuvan- Dilip
• C. Dilip- Ehsaan
• D. Chetan- Ehsaan

Answer 1

$\begin{array}{cc}\text{Name}& \text{Level of Dissimilarity}\\ \text{Amit-Bhuvan}& \text{3+2+2+1+2=10}\\ \text{Bhuvan-Dilip}& \text{1+1+1+3+2=8}\\ \text{Dilip-Ehsaan}& \text{3+0+0+3+0=6}\\ \text{Chetan-Ehsaan}& \text{0+0+2+1+3=6}\end{array}$
