Calculation of the Number of Men's Watches

To determine the number of men's watches that were brought to the store, we can use the information provided.

According to the information given, a total of 420 men's and women's watches were delivered to the store. After selling 150 men's watches and 140 women's watches, the remaining number of both types of watches became equal.

Let's assume the number of men's watches brought to the store is represented by x.

After selling 150 men's watches, the remaining number of men's watches would be x - 150.

Similarly, after selling 140 women's watches, the remaining number of women's watches would be 420 - x - 140.

According to the given information, the remaining number of both types of watches is equal. Therefore, we can set up the following equation:

x - 150 = 420 - x - 140

Simplifying the equation:

2x = 410

Solving for x:

x = 205

Therefore, the number of men's watches brought to the store is 205.

Please note that this calculation assumes that all watches delivered to the store were sold.
