the average monthly income of a family of four earning members was rs.15130. one of the daughters in the family got married and left home, so the average monthly income of the family came down to rs.14660. what is the monthly income of the married daughter?

Let's analyze the problem step-by-step.

Given Data:

• Number of earning members initially = 4
• Average monthly income initially = Rs. 130
• After one daughter leaves, number of earning members = 3
• New average monthly income = Rs. 14

What we need to find:

The income of the daughter who left.

Step 1: Calculate the total income initially

Total income initially = Average income × Number of earning members
= 130 × 4 = Rs. 520

Step 2: Calculate the total income after the daughter left

Total income after daughter left = New average income × New number of earning members
= 14 × 3 = Rs. 42

Step 3: Calculate the income of the daughter who left

Income of daughter who left = Total initial income - Total income after she left
= 520 - 42 = Rs. 478

Answer:

The daughter who got married and left home was earning Rs. 478 per month. If you want, I can explain more or solve similar problems!
