Correct Answer: Option C
Number of males in U.P
![]()
Total numbers of males in these three states
| = | | 3 | of (15% of N) | | = | 3 | x | 15 | = 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 | . |

Question 5
If in the year 1998, there was an increase of 10% in the population of U.P. and 12% in the population of M.P. compared to the previous year, then what was the ratio of populations of U.P. and M.P. in 1997 ?
Correct Answer: Option A
Let x be the population of U.P. in 1997. Then,
| Population of U.P. in 1998 = 110% of x = | 110 | x x. |
| 100 |
Also, let y be the population of M.P. in 1997. Then,
| Population of M.P. in 1998 = 112% of y = | 112 | x y. |
| 100 |
| Ratio of populations of U.P. and M.P. in 1998 |
| = |
| = | 110x | . | |||||
| 112y |
| From the pie-chart, this ratio is | 15 | . |
| 20 |
| 110x | = | 15 |  | x | = | 15 | x | 112 | = | 42 | . |
| 112y | 20 | y | 20 | 110 | 55 |
Thus, ratio of populations of U.P. and M.P. in 1997
= x : y = 42 : 55.
