** Directions (Q. 6-10): Study the following table and answer the following questions. **

**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**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**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**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

**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
