Problem Analysis

In the garden, there are 50 rose bushes. Radu watered half of the bushes, and Rodica also watered half of the bushes. However, it turns out that three rose bushes were watered twice. We need to determine how many bushes were left without watering.

Solution

Let's break down the problem step by step:

1. Initially, there are 50 rose bushes in the garden. 2. Radu watered half of the bushes, which is 25 bushes. 3. Rodica also watered half of the bushes, which is another 25 bushes. 4. However, three rose bushes were watered twice.

To find the number of bushes left without watering, we need to subtract the total number of watered bushes (including the duplicates) from the initial number of bushes.

Let's calculate it:

Total number of watered bushes = Radu's watered bushes + Rodica's watered bushes - Duplicated bushes

Total number of watered bushes = 25 + 25 - 3 = 47

Number of bushes left without watering = Initial number of bushes - Total number of watered bushes

Number of bushes left without watering = 50 - 47 = 3

Therefore, there are 3 rose bushes left without watering.

Conclusion

In the garden with 50 rose bushes, Radu watered half of the bushes, Rodica also watered half of the bushes, and three bushes were watered twice. As a result, there are 3 rose bushes left without watering.
