Please mark me as brainliest
Given: Total number of wells = 158
The number of wells that dried up = 39
The number of wells that were poisoned = 27
The number of wells that the people can live with = 130
To find: The number of wells that are mandatory to be dug
Solution: First, we need to calculate the number of wells that can no longer be used.
As such, total number of wells that cannot be used anymore = 39 + 27 = 66.
Therefore, we get the remaining number of wells = 158 - 66 = 92.
Now we need to subtract this number from the number of wells that the people of the kingdom need.
Hence, the number of wells that are mandatory to be dug = 130 - 92 = 38.
Answer: 38
