Directions : Study the following information carefully and answer the questions given beside.

In an Island called Nucolar, only two tribes Bhainaa and Koliya lives. The populatin of Bhainaa is 50% more than that of Koliya. In the island, the ratio of males to females is 11 : 9 and in Koliya tribe the number of females is 40% less than that of male population and in Bhainaa tribe, the male populations are equal to that of female populations. The total number of female populations in Koliya tribe is 1200. 
1
What is the ratio of the total population of the island to the total male populations of the Bhainaa tribe?
» Explain it
B
The following common explanation , we get

The total population of the island = 8000 
 
The total male population of Bhainaa tribe = 2400 
 
The required ratio = 8000 : 2400 = 10 : 3 
 
Hence, option B is correct.

Common explanations :

Let the population of Koliya = 2x then the ppulatin of Bhainaa = 150% of 2x = 3x ......... (i)

Let the number of males = 11a then the number of females = 9a ......... (ii)

In Koliya tribe, let the number of male = 5b then the number of female = (100 – 40)% of 5b = 60% of 5b = 3b = 1200

b = 400

the population of Koliya tribe = (5b + 3b) = 8b = 3200 = 2x (from the equation (i))

Then x = 1600

The population of Bhainaa tribe = 3x = 4800

The total population of the island = 3200 + 4800 = 8000

In Bhainaa tribe, the male population = c = the number of female populations

4800  = 2400
2

From the equation (ii)
The number of males =  11 × 8000  = 4400
20

The number of female populations =  9 × 8000  = 3600
20
2
What is the total number of male populations in the island?
» Explain it
B
The following common explanation , we get

The number of males =  11 × 8000  = 4400
20

Hence, option B is correct.

Common explanations :

Let the population of Koliya = 2x then the ppulatin of Bhainaa = 150% of 2x = 3x ......... (i)

Let the number of males = 11a then the number of females = 9a ......... (ii)

In Koliya tribe, let the number of male = 5b then the number of female = (100 – 40)% of 5b = 60% of 5b = 3b = 1200

b = 400

the population of Koliya tribe = (5b + 3b) = 8b = 3200 = 2x (from the equation (i))

Then x = 1600

The population of Bhainaa tribe = 3x = 4800

The total population of the island = 3200 + 4800 = 8000

In Bhainaa tribe, the male population = c = the number of female populations

4800  = 2400
2

From the equation (ii)
The number of males =  11 × 8000  = 4400
20

The number of female populations =  9 × 8000  = 3600
20
3
In the island, the total number male populations are how much more than that of female population?
» Explain it
D
The following common explanation , we get

The number of males =  11 × 8000  = 4400
20

The number of female populations =  9 × 8000  = 3600
20

The required difference = 4400 – 3600 = 800

Hence, option D is correct.

Common explanations :

Let the population of Koliya = 2x then the ppulatin of Bhainaa = 150% of 2x = 3x ......... (i)

Let the number of males = 11a then the number of females = 9a ......... (ii)

In Koliya tribe, let the number of male = 5b then the number of female = (100 – 40)% of 5b = 60% of 5b = 3b = 1200

b = 400

the population of Koliya tribe = (5b + 3b) = 8b = 3200 = 2x (from the equation (i))

Then x = 1600

The population of Bhainaa tribe = 3x = 4800

The total population of the island = 3200 + 4800 = 8000

In Bhainaa tribe, the male population = c = the number of female populations

4800  = 2400
2

From the equation (ii)

The number of males =  11 × 8000  = 4400
20

The number of female populations =  9 × 8000  = 3600
20
4
20% of the total population of the island are below eighteen then total how many of people are above eighteen?
» Explain it
B
The following common explanation , we get

The total population of the island = 8000 
 
The total population above eighteen = (100 – 20)% of 8000 = 80% of 8000 = 6400 
 
Hence, option B is correct.

Common explanations :

Let the population of Koliya = 2x then the ppulatin of Bhainaa = 150% of 2x = 3x ......... (i)

Let the number of males = 11a then the number of females = 9a ......... (ii)

In Koliya tribe, let the number of male = 5b then the number of female = (100 – 40)% of 5b = 60% of 5b = 3b = 1200

b = 400

the population of Koliya tribe = (5b + 3b) = 8b = 3200 = 2x (from the equation (i))

Then x = 1600

The population of Bhainaa tribe = 3x = 4800

The total population of the island = 3200 + 4800 = 8000

In Bhainaa tribe, the male population = c = the number of female populations

4800  = 2400
2

From the equation (ii)
The number of males =  11 × 8000  = 4400
20

The number of female populations =  9 × 8000  = 3600
20
5
The total number of female population in Bhainaa tribe is how much percentage more than that of Koliya tribe?
» Explain it
E
The following common explanation , we get

The total number of female population in Bhainaa tribe = 2400

The total number of female population in Koliya tribe = 1200

The reqd. % =  (2400 – 1200) × 100  = 100%
1200

Hence, option E is correct.

Common explanations :

Let the population of Koliya = 2x then the ppulatin of Bhainaa = 150% of 2x = 3x ......... (i)

Let the number of males = 11a then the number of females = 9a ......... (ii)

In Koliya tribe, let the number of male = 5b then the number of female = (100 – 40)% of 5b = 60% of 5b = 3b = 1200

b = 400

the population of Koliya tribe = (5b + 3b) = 8b = 3200 = 2x (from the equation (i))

Then x = 1600

The population of Bhainaa tribe = 3x = 4800

The total population of the island = 3200 + 4800 = 8000

In Bhainaa tribe, the male population = c = the number of female populations

4800  = 2400
2

From the equation (ii)
The number of males =  11 × 8000  = 4400
