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

### Instruction:
P2: On the first day, Chris holds his breath for 10 seconds. On the second day, he holds it for 20 seconds. On the third day, he holds it for 30 seconds. Each day, he increases his breath-holding time by 10 seconds. 
To find out how many days it will take for him to reach 90 seconds, we can set up an equation: 
10 + 20 + 30 + 10x = 90, where x represents the number of additional days. 
Simplifying the equation, we get: 
60 + 10x = 90 
Subtracting 60 from both sides, we get: 
10x = 30 
Dividing both sides by 10, we get: 
x = 3 
Therefore, it will take Chris 3 additional days to reach a breath-holding time of 90 seconds.
