Solution
The correct option is D (d) Rs. 655
To minimize cost of trip most passengers would be taken by the type of bus that cost the least per passenger.
So, to the extent that full capacity of a bus can be utilized maximum number of passengers should be taken by Q type bus. 200 passengers would require four buses. Then 20 passengers remain, who may be taken by one S type bus.
Total cost 140 x 4 + 95 = 560 + 95 = 655
