Options

A. 80
B. 60
C. 40
D. 120

Answer

To find the number of girls in the school, we can follow these steps:

### Step 1: Determine the number of boys
We know that there are a total of 200 students in the school, and that \(\frac{7}{10}\) of them are boys.

To find the number of boys, we can calculate:
\[ \text{Number of boys} = \frac{7}{10} \times 200 \]

### Step 2: Calculate the number of boys
Now let's perform the multiplication:
\[ \text{Number of boys} = \frac{7 \times 200}{10} = \frac{1400}{10} = 140 \]

### Step 3: Determine the number of girls
Now that we know the number of boys, we can find the number of girls by subtracting the number of boys from the total number of students:
\[ \text{Number of girls} = \text{Total students} - \text{Number of boys} \]
\[ \text{Number of girls} = 200 - 140 = 60 \]

### Final Answer
Thus, the number of girls in the school is \(60\).
