Directions to Solve
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 |
1.
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  x = |
5 x 100 x 1.9 | = 6.25. |
| 5 | 100 | 76 x 2 |
Total population of State R = 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.

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.

How you got x = 0.8? Explain.
How you got x = 0.8? Explain.

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.

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.
