Question 86

A school in Chennai is planning for an excursion tour for its students. They want to show them KANYAKUMARI, VIZAG, and BHUBANESWAR, not necessarily in the same order. What is the minimum travel cost (in RS.) the school should charge from each of the student for the entire tour?


The minimum cost incurred in all of the options is Rs. 4300. For minimum amount travelling, school should plan to travel by ship or train route.
So possible routes for Kanyakumari, Vizag and Bhubaneshwar.
Chennai ----Ship (950) ---> Bhubanehswar ----Ship (700)---> Kanyakumari ----Ship (250) ---> Vizag --- Train (300) ---> Chennai
Total cost = 950 × 1.5 + 700 × 2.5 + 250 × 1.5 + 300 × 2.5
= 1425 + 1750 + 375 + 750 = `Rs. 4300.
Therefore, option A is the correct answer.
