1)Ans-d)
Total population of each of state in not given .
2) If the female population blow poverty line in state D is 6.3 million , find the female population above poverty line ?
a) 38 million b)28 million c)25 million d)32 million

2)Ans-b)28million
Percentage population above poverty line is given =84%
so, % population below poverty line is =16%
9/16 of 16% =6.3 million
9% = 6.3 million
= > 10/21 x84% =40% = > 6.3/9 x40% = 28 million
3)If the female population above poverty line in state A is 3.6 million more than the female population above poverty line in state D , find the difference between total population of state A and state D ?
a) 9 million b)10 million c) 19 million d) can’t say

3) Ans-a)9million
At, 1st glance data seems in adequate for question .
Let, total population of state A and state D is X and Y respectively ,
Female population above poverty line in state A = 5/9 of 72% of X = 40% of X
Female population above poverty line in state D = 10/21 of 84% of Y = 40% of y
According to the qus,
40%of x – 40% of Y = 3.6
40% (X-Y ) =3.6
== >X-Y = 9million
NOTE: If the percentages are different we can’t solve the problem .
4) If the percentage of male population below the poverty line in state C and state E together is 15% , find the % male population above poverty line in state C and E together ?
a) 35.5% b)32.4% c) 37.8% d)can’t

4) Ans-b)32.4%
Percentage of male population below poverty line in state C = 6/11 of 44 % =24%
And that in state E = 5/12 of 24% = 10%
Combining both state we have 15% male population below poverty line ,obviously 15% is weighted mean of 24% and 10%
So,
C E
24% ———–10%
——–15%———
5%—————9%
Therefore, total population of C and E are in ratio = 5:9
Now % of male population above poverty line in state C =13/28 of 56% = 26%
That in state E = 9/19 of 76% = 36%
Required percentage = (26×5 + 36x 9) /5+9 = 130+324 /14 = 454 /14 = 32.4 %
5)If the female population above poverty line in state C is greater than the female population above poverty line in state B , which of the following definitely true ?
a) population of C > population of B
b) population of C< population of B
c) population of C= population of B
d) can’say .

5)Ans- d)can’t say
Let the total population of state C and state B be X andY respectively ,
According to qus ,
15/28 of 56% of X > 7/16 of 64% of Y
== > 30% of X > 28% of Y
So, X >Y or X<Y or X=Y,
