Answer:
✏The correct option is B Rs 73,333
Per capita income is the sum of all income sources, divided by the total number of people. Here the gross income of the family is = Rs (1,80,000+ 40,000) = Rs 2,20,000, the pocket money won't be added as it is an expense for the family. Then the per capita income of the family= Gross income / 3 (as the family has three members) = Rs 73,333.
Step-by-step explanation:
Percent is a relative quantity. Earning of our family is more than our friend's family (on monthly basis), by 11.11% approximately. (compared to friend's family's monthly income)
How to find how much percent 'a' is of 'b'?
Percent is a relative quantity, as it is the measure of one quantity per 100 units of other quantity.
- Suppose a number is 'a'
- Suppose another number is 'b'
We want to know how much percent of 'b' is 'a'.
Then, it is calculated as:
[tex]\dfrac{a}{b} \times 100[/tex]
(in percentage)
For this case, we're specified that:
For our family:
- Income of father = ₹ 40,000
- Income of mother = ₹ 35,000
- Income of brother = ₹ 25,000
Total monthly income = ₹(40000 + 35000 + 25000) = ₹100,000
For friend's family:
- Income of father = ₹ 45,000
- Income of mother = ₹ 30,000
- Income of brother = ₹ 15,000
Total monthly income = ₹(45000 + 30000 + 15000) = ₹90,000
Thus, we see that friend's family's monthly is monthly ₹10,000 less than our family's monthly income.
We need to find how much percent this ₹10,000 is of their family because we need to find by how much percent our family's income is more than the friend's family's monthly income (so comparison is with respect to the monthly income of friend's family).
Let P be the percent the ₹10,000 is of the amount ₹90,000
Then, we get:
[tex]P = \dfrac{10000}{90000} \times 100 = \dfrac{100}{9} \approx 11.11 \%[/tex]
Thus, earning of our family is more than our friend's family (on monthly basis), by 11.11% approximately. (compared to friend's family's monthly income)
