Ravish paid ₹640 for a jar of 40 chocolates where the amount paid included the cost of the jar. Harish paid a total of ₹1540 for one jar containing 55 chocolates and a second jar containing 45 chocolates, where the amount paid included the cost of both the jars. If all jars cost the same, and all chocolates cost the same, how much (in ₹) would Satish have to pay for a jar containing 35 chocolates, if the amount he has to pay includes the cost of the jar as well as that of the chocolates he bought?

75 people are stranded on an island, and they have sufficient food for 100 days. After 10 days, two-third of the people separate from the group in search of a way out. After another 16 days, 25 people return. From this day on, how many days will the food last?

Imagine a magical donation box that can only accept tokens of 100, 250, and 500 gold coins.

Like a mission to maximize the loot, determine the highest possible number of 500-gold-coin tokens that the donation box could have contained.
