Directions (Q. 6-10): Study the following table and answer the following questions. 1. If the population of females below poverty line in city D is 24000, then the population of males above poverty line in that city is:
A) 62400
B) 93600
C) 70000
D) 130000
E) None of these
B) 93600
Explanation:

Note – in all these questions, see that we are only given a % of people living below poverty line out of total people in that city.
Let total people below poverty line = x
In D, females below poverty line is 6/(5+6) * x
So 6/11 * x = 24000, x = 44,000
Let total population in city D is y
Then 22% of y = 44,000
Solve, y = 200,000
So population above poverty line = 200,000 – 44,000= 156,000
So males above poverty line = 3/(3+2) * 156000 = 93600

2. If the total population of city A is 300,000, then the difference of number of males below poverty line and number of females above poverty line in this city is
A) 54000
B) 74400
C) 68400
D) 93600
E) None of these
C) 68400
Explanation:

In A, popu. below poverty line = 18/100 * 300,000 = 54000, so males below poverty line = 5/9 * 54000 = 30,000
Pop. above poverty line = 300,000 – 54,000 = 246,000, so females above poverty line = 2/5 * 246,000 = 98400
So diff = 98400 – 30000 = 68400

3. If the total population of city B and city C is 500000 and 350000 respectively, the ratio of number of females below poverty line in B and C is
A) 28 : 35
B) 6 : 7
C) 16 : 21
D) 7 : 6
E) None of these
C) 16 : 21
Explanation:

In B, below poverty line = 14/100 * 500,000 = 70,000, so females below poverty line = 4/7 * 70,000 = 40,000
In C, below poverty line = 25/100 * 350,000 = 87,500, so females below poverty line = 3/5 * 87,500 = 52,500
Ratio = 40,000 : 52,500

4. If the population of males below poverty line in city F is 32000 and that in city E is 39000, then what percent of total population of E is total population of F ?
A) 61.54
B) 90.22
C) 82.05
D) 71.45
E) None of these
A) 61.54
Explanation:

Let people below poverty line in F = x, so 4/9 * x = 32000
Solve, x = 72,000
18/100 * y = 72,000
Solve, y = 400,000 = total pop. in F
Let people below poverty line in E = x, so 3/5 * x = 39000
Solve, x = 65,000
10/100 * y = 65,000
Solve, y = 650,000 = total pop. in E
Required % = 400,000/650,000 * 100 = 61.54

5. What is the sum of the number of females below poverty line and number of males above poverty line in city D if population is 24000?
A) 12122
B) 13426
C) 11232
D) 14112
E) None of these
D) 14112
Explanation:

People below poverty line = 22/100 * 24000 = 5280, so females below poverty line = 6/11 * 5280 = 2880
People above poverty line = 24000 – 5280 = 18720, so males above poverty line = 3/5 * 18720 = 2880 = 11232
Total = 2880+11232 = 14112
