B. ₹ 28000
C. ₹ 32000
D. ₹ 31750

Answer

To find the average income of a family of 4 members, we will follow these steps:

### Step 1: Identify the monthly earnings of each family member.
- Father's income = ₹50,000
- Mother's income = ₹32,000
- Son's income = ₹25,000
- Daughter's income = ₹20,000

### Step 2: Calculate the total income of the family.
To find the total income, we will add the incomes of all family members together:

\[ \text{Total Income} = \text{Father's Income} + \text{Mother's Income} + \text{Son's Income} + \text{Daughter's Income} \]

Substituting the values:

\[ \text{Total Income} = 50,000 + 32,000 + 25,000 + 20,000 \]

### Step 3: Perform the addition.
Now, we will perform the addition step by step:

1. Add the father's and mother's income:
\[ 50,000 + 32,000 = 82,000 \]

2. Add the son's income:
\[ 82,000 + 25,000 = 107,000 \]

3. Finally, add the daughter's income:
\[ 107,000 + 20,000 = 127,000 \]

So, the total income of the family is ₹127,000.

### Step 4: Determine the number of family members.
The family consists of 4 members.

### Step 5: Calculate the average income.
The average income is calculated by dividing the total income by the number of family members:

\[ \text{Average Income} = \frac{\text{Total Income}}{\text{Number of Family Members}} \]

Substituting the values:

\[ \text{Average Income} = \frac{127,000}{4} \]

### Step 6: Perform the division.
Now, we will perform the division:

\[ \text{Average Income} = 31,750 \]

### Conclusion:
The average income of the family is ₹31,750.
