The average income of a family of 6six members is five thousands. The income of two of them is twelve thousands. What is income of the remaining three persons?
Answers
Answer:
1st to find income of family then when we will subtract income of family to income of 2 members we will get income of 4 remaining members so income of 4 members will be same so income/4 means the income of single member
Then if we multiply by 3 we gets income of 3 members
6 members income =5000 x 6
=30000
2 members income =12000
4 members income =30000-12000
=18000
3 members income =18000/4
=4500
=4500 x 3
=13500
Complete question:
The average income of a family of six members is five thousand. The income of two of them is twelve thousands. What is the income of the remaining four persons?
Answer:
The total income of the remaining 4 members = 18,000
Step-by-step explanation:
Given,
The average income of a family of 6 members = 5000
Income of two members of the family = 12,000
To find,
The income of the remaining four members of the family
Solution:
Recall the formula
Average =
since the average income of a family of 6 members = 5000, we have
= 5000
Total income of 6 members of the family = 5000× 6 = 30,000
Total income of two members + Total income of remaining 4 members = 30,000
Since the income of two members is given as 12,000, we have
12,000+Total income of the remaining 4 members = 30,000
Total income of the remaining 4 members = 30,000 - 12,000
= 18,000
∴ The total income of the remaining 4 members = 18,000
