Study the following graph and the table and answer the questions given below.

Data of different states regarding population of states in the year 1998

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

1.
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?
25%
27.5%
28.5%
31.5%
Explanation:

 Number of males in U.P = 3 of (15% of N) = 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

Total number of males in these three states
 = (9 + 15 + 4.5) x N 100
 = 28.5 x N . 100

Required Percentage =
 28.5 x N 100
x 100 % = 28.5%.
N

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%.

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

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.

Shailesh said:   1 decade ago

UP - 15%.

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.
