The average income per person for a family of 5 members is rs.8,000 per month. In a particular month, every member got rs.800 less than the usual. What is the average income er person for that month?

Answer 1

total income=
$= > 8000 \times 5 \\ = > 40000$
if 5 members got ₹800 less
so decrease in total income=
$= > 40000 - (800 \times 5) \\ = > 40000 - 4000 \\ = > 36000$
now total income is ₹36000
total member are 5
then average income=
$= > 36000 \div 5 \\ = > 7200$
the answer is ₹7200
