Total population of the given States = 3276000.
| States | Sex and Literacy wise Population Ratio | |||
| Sex | Literacy | |||
| M | F | Literate | Illiterate | |
| A.P | 5 | 3 | 2 | 7 |
| M.P | 3 | 1 | 1 | 4 |
| Delhi | 2 | 3 | 2 | 1 |
| Goa | 3 | 5 | 3 | 2 |
| Bihar | 3 | 4 | 4 | 1 |
| U.P. | 3 | 2 | 7 | 2 |
| T.N. | 3 | 4 | 9 | 4 |

What will be the percentage of total number of males in U.P., M.P. and Goa together to the total population of all the given states?
Answer: Option
Explanation:
| Number of males in U.P = |  |
3 | of (15% of N) | ![]](/_files/images/data-interpretation/common/15-sym-cbracket-h1.gif) |
= | 3 | x | 15 | x N = 9 x | N | . |
| 5 | 5 | 100 | 100 |
where N = 3276000.
| Number of males in M.P = | |
3 | of (20% of N) | |
= | 3 | x | 20 | x N = 15 x | N | . |
| 4 | 4 | 100 | 100 |
| Number of males in Goa = | |
3 | of (12% of N) | |
= | 3 | x | 12 | x N = 4.5 x | N | . |
| 8 | 8 | 100 | 100 |

First, find a total number of males.
UP = 3/5 * (15% of 3276000) = 294840
MP = 3/4 * (20% of 3276000) = 491400
GOA = 3/8 * (12% of 3276000) = 147420
Now % = total no. Of males(UP + MP + GOA) divide by 3276000* 100.
= 28.5%.
UP = 3/5 * (15% of 3276000) = 294840
MP = 3/4 * (20% of 3276000) = 491400
GOA = 3/8 * (12% of 3276000) = 147420
Now % = total no. Of males(UP + MP + GOA) divide by 3276000* 100.
= 28.5%.

Why we have to add 3+2 in the first step?

U.P (Male, Female ratio) = 3 : 2 = 3/(3 + 2) = 3/5.
M.P = 3:1 = 3/4.
Goa = 3:5 = 3/8.
We know that 3276000 value remains same for all states.
So, take only the percentages and assume 3276000 as 'N'.
U.P = Population percentage = 15%.
M.P = 20%.
Goa = 12%.
No of men in U.P = 3/5 (15/100) N = (9/100) N.
M.P = 3/4 (20/100) N = (15/100) N.
Goa = 3/8 (12/100) N = (4.5/100) N.
Adding these three, we get (28.5/100) N.
Required % = {(28.5/100)N/N } * 100 = 28.5%.
M.P = 3:1 = 3/4.
Goa = 3:5 = 3/8.
We know that 3276000 value remains same for all states.
So, take only the percentages and assume 3276000 as 'N'.
U.P = Population percentage = 15%.
M.P = 20%.
Goa = 12%.
No of men in U.P = 3/5 (15/100) N = (9/100) N.
M.P = 3/4 (20/100) N = (15/100) N.
Goa = 3/8 (12/100) N = (4.5/100) N.
Adding these three, we get (28.5/100) N.
Required % = {(28.5/100)N/N } * 100 = 28.5%.

In the question they didn't mention that the men and female are in the ratio.

How 3/5 comes at first step?
Ans:
Ratio of males and females in UP = 3 : 2
Number of Males = 3/(3+2) = 3/5 of 15% of N.
Ans:
Ratio of males and females in UP = 3 : 2
Number of Males = 3/(3+2) = 3/5 of 15% of N.

Directly we can take the male percentages to total.
i.e. U.P. Male = 3% of 15% 3276000.
Like this we can take M.P and GOA then we add.
