Answers 1: (b) Dissimilarity is the maximum difference between the ranks allotted by the city’s population to any particular category. For example, London and New York have a dissimilarity of (4-1=3) in the ‘C’ category. Another example, dissimilarity between New York and Berlin: From the above table the maximum difference is 2. ∴ The dissimilarity level between New York and Berlin is 2.

Hence from the similar calculations, the highest level of dissimilarity is 4 which is for Sydney and New York in ‘D’ category. The correct option is (b).

Answers 2: (d) Checking each option pair one by one The level of dissimilarity between Berlin and Sydney is for the parameter D (4 –1) = 3 New York and Berlin is for the parameter N (3 –1) = 2 London and Sydney is for the parameter V (4 – 1) = 3 Goa and Sydney is for the parameter D (5 –1) = 4 The correct option is (d).

Answers 3: (d) The level of dissimilarity between London and Berlin is for the parameter V (5 – 1) = 4 Berlin and Goa is for the parameter V (5 –1) = 4 Goa and Sydney is for the parameter D (5 –1) = 4 Sydney and London is for the parameter V (4 – 1) = 3

Hence the last option is the odd one out. The correct option is (d).

Answers 4: (a) Calculating the level of dissimilarity for New York with remaining cities Berlin : For the parameter N (3 –1) = 2 Sydney : For the parameter D (5 –1) = 4 London : For the parameter C (4 –1) = 3 Goa : For the parameter V (4 –1) = 3 ∴ The least level of dissimilarity is 2 which is for Berlin. The correct option is (a).
