Shyam prepares and sells piping hot puri and sabji (gravy) from 7:00 am to 9:00 am (both inclusive) through a stall at XLRI campus. Presently, he has just a single oven, which can do only one job at a time. It takes 30 minutes to cook one handi (a large bowl) of sabji, sufficient for 12 customers. It takes him 10 minutes to prepare 2 plates of puri at a time. While the cost of a plate of puri-sabji is ₹ 10, the price is ₹ 25. Puri stays hot for only 5 minutes after preparation, while sabji stays hot for 30 minutes only. It takes 10 minutes to reheat the sabji which stays hot for another 30 minutes. If he brings a handi of hot sabji from home, the transport would cost him ₹ 50. It can also stay hot for 30 minutes excluding the transportation time. Currently, every 20 minutes five plates are ordered. All unsold quantities are distributed at cost after 9:30 am.
Shyam’s puri-sabji became famous. Now he gets 5 orders per 10 minutes and has invested in an additional oven. As he is working alone on both the ovens simultaneously, now in any one oven it takes him 45 minutes to cook one handi of sabji,15 minutes for 2 plates of puri and 15 minites to reheat the sabji. He can bring only one handi from home. What will be his maximum daily profit?
Since he already has one handi of sabji, he will invest the first 30 minutes of starting time in making puris in the oven.
As 1 oven cooks 2 plates of puris in 15 minutes, in the first 30 minutes, he will be able to prepare 8 plates of puris.
Total plates of Puri = 11*2
Now, profit = 15 × 22 = 330 - 50 (Transport cost) = 280
Thus, the correct answer is B.
