The average monthly income of a family of four earning members was Rs. 15,130. One of daughters in the family got married and left home, so the average monthly income of the family come down to Rs. 14,660. What is monthly income of the married daughter?

Answer

To find the monthly income of the married daughter, we can follow these steps:

### Step 1: Calculate the total income of the family before the daughter got married.
The average monthly income of the family of four earning members is given as Rs. 15,130. To find the total income, we multiply the average income by the number of members.

\[ \text{Total Income before} = \text{Average Income} \times \text{Number of Members} = 15,130 \times 4 = 60,520 \]

### Step 2: Calculate the total income of the family after the daughter got married.
After the daughter got married, the family has three earning members left, and the new average monthly income is Rs. 14,660. We can find the total income of the remaining family members.

\[ \text{Total Income after} = \text{Average Income after} \times \text{Number of Remaining Members} = 14,660 \times 3 = 43,980 \]

### Step 3: Calculate the monthly income of the married daughter.
To find the monthly income of the married daughter, we subtract the total income of the remaining family members from the total income before she got married.

\[ \text{Income of Married Daughter} = \text{Total Income before} - \text{Total Income after} = 60,520 - 43,980 = 16,540 \]

### Conclusion:
The monthly income of the married daughter is Rs. 16,540.
