Answers
Given : There are 100 families in a country,
the average per capita income of these families is ₹ 10,000
the average per capita income of 50 of these families is 5000.
To Find : The average per capita income of the remaining families is
(a) ₹ 5000
(b) ₹ 10000
(c) ₹ 15000
(d) ₹ 20000
Solution:
Number of Families = 100
average per capita income of 100 Families = Rs 10000
Total Capita Income of 100 Families = 100 * 10000 = 1000000 Rs
the average per capita income of 50 of these families is 5000.
=> Capita Income of 50 families = 50 * 5000 = 250000 Rs
Remaining Families = 100 - 50 = 50
Remaining capita income = 1000000 - 250000 = 750000 Rs
The average per capita income of the remaining families = 750000/50
= 15000 Rs
Correct option is (c) rupees 15000
