Detailed Solution

Concept: 18 cows can graze the same field in 15 days. Twenty days will be enough time for 24 cows to graze on the field. We first determine how many cows are needed to graze the area in a single day, and then we multiply that number by 15 to determine how many cows are needed to graze the same field over the course of 15 days. To answer the question, we employ unitary approaches. Using the unitary method, we first determine the value of a single unit before multiplying that value to determine the needed value.
We've been told that a field can support 24 cows for 20 days of grazing.
The number of cows needed to graze the same pasture for 15 days must be determined.
We use the unitary technique to answer this query. We will start by determining how many cows are needed to graze the pasture for an entire day.
Now, 2420 cows will be needed to graze the same land in a single day.
Now, we multiply the aforementioned figure by 15 to get the desired result.
Therefore, 2420 x 15 = 18 cows are needed to graze the same land for 15 days.
Therefore, in 15 days, 18 cows can graze in the same field.
Hence, the answer is 18 cows.
