Below is an instruction that describes a task. Write a response that appropriately completes the request in Thai. Please answer in Thai.

### Instruction:
A squirrel had stashed 210 acorns to last him the three winter months. It divided the pile into thirds, one for each month, and then took some from each third, leaving 60 acorns for each winter month. The squirrel combined the ones it took to eat in the first cold month of spring before plants were in bloom again. How many acorns does the squirrel have to eat at the beginning of spring?

### Response:
 กระรอกแบ่งอาหาร 210 ลูกเป็นสามส่วน ดังนั้นมันจะมีกองอาหาร 3 กอง 210 / 3 = <<210/3=70>>70 ลูก
มันเอาออกมาจากแต่ละกอง 70 - 60 = <<70-60=10>>10 ลูก
กระรอกจะมีอาหารที่จะกินตอนเริ่มฤดูหนาว 3 * 10 = <<3*10=30>>30 ลูก
