The following table gives the percentage distribution of population of five states, P, Q, R, S and T on the basis of poverty line and also on the basis of sex.
State | Percentage of Population below the Poverty Line | Proportion of Males and Females | |
Below Poverty Line | Above Poverty Line | ||
M : F | M : F | ||
P | 35 | 5 : 6 | 6 : 7 |
Q | 25 | 3 : 5 | 4 : 5 |
R | 24 | 1 : 2 | 2 : 3 |
S | 19 | 3 : 2 | 4 : 3 |
T | 15 | 5 : 3 | 3 : 2 |

If the male population above poverty line for State R is 1.9 million, then the total population of State R is?
Answer: Option
Explanation:
Let the total population of State R be x million.
Then, population of State R above poverty line
= [(100 - 24)% of x] million
= | ![]() |
76 | x x | ![]() |
million |
100 |
And so, male population of State R above poverty line
= | ![]() |
2 | x | ![]() |
76 | x x | ![]() |
![]() |
million |
5 | 100 |
But, it is given that male population of State R above poverty line = 1.9 million.
![]() |
2 | x | ![]() |
76 | x x | ![]() |
= 1.9 ![]() |
5 x 100 x 1.9 | = 6.25. |
5 | 100 | 76 x 2 |
Total population of State R = 6.25 million.

Its Easy, just find X more than enough,
Data given:- M:F ratio above the poverty line is 2:3 and Total male population above the poverty line is 1.9.
Therefore, In the above poverty line,
Ratios are 2:3 i.e, 2x:3x which is no. of males are 2x= 1.9 so, x = 0.8
So, no of females is 3x i.e, 3*0.8 = 2.4.
Similarly, In below poverty line,
M:F ratio is 1:2.
Take the same X value x=0.8 and substitute in 1x:2x
1x=0.8, x = 0.8
2x = 2(0.8) = 1.6.
Now, add both above poverty and below poverty line values that is;
1.9 + 2.4 + 0.8 + 1.6 = 6.7 approx 6.2.
Data given:- M:F ratio above the poverty line is 2:3 and Total male population above the poverty line is 1.9.
Therefore, In the above poverty line,
Ratios are 2:3 i.e, 2x:3x which is no. of males are 2x= 1.9 so, x = 0.8
So, no of females is 3x i.e, 3*0.8 = 2.4.
Similarly, In below poverty line,
M:F ratio is 1:2.
Take the same X value x=0.8 and substitute in 1x:2x
1x=0.8, x = 0.8
2x = 2(0.8) = 1.6.
Now, add both above poverty and below poverty line values that is;
1.9 + 2.4 + 0.8 + 1.6 = 6.7 approx 6.2.

We can do this example same as example no. 3:
Ratio between male & female for above poverty line is 2:3.
Lets assume female population above poverty line is x.
So, 2:3 = 1.9:x => x = 2.85 million.
Total population above poverty line = 1.9 + 2.85 = 4.75 million.
Now the ratio of Population below poverty line & above poverty line is 24:76.
Lets assume population of below poverty line is y.
So, 24:76 = y:4.75 => y = 1.50 million.
Total population of state R = 4.75 + 1.50 = 6.25 million.
Ratio between male & female for above poverty line is 2:3.
Lets assume female population above poverty line is x.
So, 2:3 = 1.9:x => x = 2.85 million.
Total population above poverty line = 1.9 + 2.85 = 4.75 million.
Now the ratio of Population below poverty line & above poverty line is 24:76.
Lets assume population of below poverty line is y.
So, 24:76 = y:4.75 => y = 1.50 million.
Total population of state R = 4.75 + 1.50 = 6.25 million.

Below poverty line 1:2 is 24%.
Above poverty line is 2:3.
Here 2 which is male ratio is given 1.9mill. So find 3? in mill.
2/3=1.9/x.
Cross multiply 2x = 5.7.
X= 2.85 which is female ratio 3.
Now add total population of above poverty line male + female
= 1.9+2.85.
= 4.75 mill.
Now since 24% is below poverty line then 24-100 = 76% is above poverty line.
76% is = 4.75mill,
Now 24% = 4.75/76*24.
= 1.5mill.
Now total population = 1.5 + 4.75.
= 6.25mill.
Above poverty line is 2:3.
Here 2 which is male ratio is given 1.9mill. So find 3? in mill.
2/3=1.9/x.
Cross multiply 2x = 5.7.
X= 2.85 which is female ratio 3.
Now add total population of above poverty line male + female
= 1.9+2.85.
= 4.75 mill.
Now since 24% is below poverty line then 24-100 = 76% is above poverty line.
76% is = 4.75mill,
Now 24% = 4.75/76*24.
= 1.5mill.
Now total population = 1.5 + 4.75.
= 6.25mill.

It means,
Percentage of the Population below the Poverty Line Means the Proportion of Males and Females Below the Poverty Line which is 24% and Ration of 1:2,
Similarly,
Percentage of the Population Above the Poverty Line Means the Proportion of Males and Females Above the Poverty Line which is 76% and Ration of 2:3,
Now,
2 = 1.9.
5 = 1.9/2 * 5 = 4.75 (It is 76%).
So,
76% = 4.75
100% = 4.75/76 * 100 = 6.25 Millions.

Percentage of the Population Above the Poverty Line Means the Proportion of Males and Females Above the Poverty Line which is 76% and Ration of 2:3,
Now,
2 = 1.9.
5 = 1.9/2 * 5 = 4.75 (It is 76%).
So,
76% = 4.75
100% = 4.75/76 * 100 = 6.25 Millions.

Hi @Anand,
Yes, above poverty line for the state R is 2:3, in that 2 is males percentage, and 3 is females percentage and 5 (2+3) is the overall population including male and female. if you need to find the male population alone of State R then it would be 2/(2+3) = 2/5; similarly for female population 3/(2+3) = 3/5.
Hope this is clear.

% in the r state bellow the poverty line is 24 hence the % of above poverty line in r state will be 76% the proportion between male and female in above poverty line is 2:3 the male population above the poverty line in r state is 1.9 million.
Hence 76% 2/5 = 1.9 million.
76% = 9.5/2, 76% = 4.75 million and 100% will be 6.25 million.
Hence 76% 2/5 = 1.9 million.
76% = 9.5/2, 76% = 4.75 million and 100% will be 6.25 million.

Male population above poverty line = 1.9.
Ratio of m/f above poverty line = 2/3.
Now 1.9/f=2/3.
Female population=2.85
Total population above poverty line = 2.85+1.9 = 4.75.
Total percentage above poverty line = 76(100-240),
Now let total population be x.
76 % 0f x=76/100*x = 4.75.
x = 6.25 ans.
Ratio of m/f above poverty line = 2/3.
Now 1.9/f=2/3.
Female population=2.85
Total population above poverty line = 2.85+1.9 = 4.75.
Total percentage above poverty line = 76(100-240),
Now let total population be x.
76 % 0f x=76/100*x = 4.75.
x = 6.25 ans.

Here above poverty line of are is 24, we take this number as 24% means 24/100.
In this 24/100, 24 is the numerator and 100 is the denominator. So the difference between these two numbers is 76.
In this 24/100, 24 is the numerator and 100 is the denominator. So the difference between these two numbers is 76.

It can be done more easily:
(1.9/2) * 5 = 4.75
as 4.75 is 76%(100-24)% of total population, so total population is (4.75/76)*100 = 6.25 million
(1.9/2) * 5 = 4.75
as 4.75 is 76%(100-24)% of total population, so total population is (4.75/76)*100 = 6.25 million
