Options

A. 173
B. 143
C. 153
D. 163

Answer

To find the number of students belonging to other communities, we can follow these steps:

### Step 1: Calculate the percentage of students belonging to other communities.
We know the percentages of students from the three communities:
- Muslims: 44%
- Hindus: 28%
- Sikhs: 10%

To find the percentage of students from other communities, we subtract the sum of these percentages from 100%.

\[ \text{Percentage of other communities} = 100\% - (44\% + 28\% + 10\%) \]

### Step 2: Perform the calculation.
First, calculate the sum of the percentages of Muslims, Hindus, and Sikhs:

\[ 44\% + 28\% + 10\% = 82\% \]

Now, subtract this from 100%:

\[ \text{Percentage of other communities} = 100\% - 82\% = 18\% \]

### Step 3: Calculate the number of students from other communities.
Now that we have the percentage of students from other communities, we can find the actual number of students by calculating 18% of the total number of students (850).

\[ \text{Number of students from other communities} = \frac{18}{100} \times 850 \]

### Step 4: Perform the multiplication.
Calculating the above expression:

\[ \text{Number of students from other communities} = 0.18 \times 850 = 153 \]

### Final Answer:
There are **153 students** from other communities.
