Answer:
Option E
Explanation:
We analyse the given information as follows:
Two are hill stations. Three are plains of which two are harbours. Four towns are capitals. Two towns are industrial. TWo towns have a population less than 5 lacs.One town has a population 20 lacs. Two towns have a population of more than 50 lacs. Two towns are on same latitudes.
B is a hill station. E is a harbour. Clearly, A which has the same longitude as E, cannot be a harbour and clearly, D having a population 20 lacs cannot be an industrial town. So, it is a harbour. Thus, E and D are harbours.
Clearly, one harbour is an industrial town but D is not. So, E is an industrial town with population more than 50 lacs. Clearly, the longitudes of a hill station and industrial town are same. So, A having same longitude as E, is hill station. Latitudes of D and C are same and D is a harbour. So, C cannot be a hill station. So, B is the other hill station. Thus, three plains are C, D, E. One industrial town is neither a hill station nor a harbour. So, C is an industrial town with a population more than 50 lacs. Clearly, both harbours are capitals. So, E and D are capitals.The hill station A, having same longitude as a harbour, is also a capital. The population of D is 20 lacs. So, population of A and B is less than 5 lacs. Clearly, only one hill station is capital. So, C is the other capital.
The capitals are A, C, D and E. The hill stations are A and B. So, A is a hill station as well as a capital.
