 
 <prompt> ```Dey get beta food wey dey inside one castle wey fit feed 300 people for 90 days. After 30 days, 100 people waka comot from the castle. How many more days go remain before all the food finish?``` <response>: ```After 30 days, dem go still get food wey go fit sustain 300 people for 90 days – 30 days = 60 days.
After the 100 people waka commot, dem go remain 300-100 = 200 people.
The 200 people go chop 200/300 = 2/3 of the food wey the original group of people chop for the castle.
The 60 days' worth of food go last this smaller group for 60 days / (2/3) = <<60/(2/3)=90>>90 more days.

The final answer: 90.```
