Total provisions=600*26*7=109200

Provisions used for in 6 weeks=6*7*600=25200

remaining provisions=84000

remaining provisions need to be split between 900(600+300) people.

Number of provisions per person= 84000/900

we need to find the answer in terms of weeks=(84000/900)/7=131/3

Answer:A

Hope it helps!
