To find the income of the fourth family, we'll use the formula for average income: Average income = Total income / Number of families Given: Average per capita income of the four families = ₹5000 Total income of the three families = ₹4000 + ₹7000 + ₹3000 = ₹14000 Number of families = 3 (since incomeRead more
To find the income of the fourth family, we’ll use the formula for average income:
Average income = Total income / Number of families
Given:
Average per capita income of the four families = ₹5000
Total income of the three families = ₹4000 + ₹7000 + ₹3000 = ₹14000
Number of families = 3 (since income information is given for only three families)
Let the income of the fourth family be ‘x’.
Average income = Total income / Number of families
₹5000 = (₹14000 + x) / 4 (as there are four families in total)
₹5000 * 4 = ₹14000 + x
₹20000 = ₹14000 + x
x = ₹20000 – ₹14000
x = ₹6000
Therefore, the income of the fourth family is ₹6000.
