Direction: A table showing the percentage of the total population of a State by age groups for the year 1991 is given below. Answer the questions given below it.

  1. If the difference between the number of people in the age groups (46 – 55) and (26 – 35) is 11.75 millions, then the total population of the State is approximately :
    1. 360.23 millions
    2. 391.67 millions
    3. 400 millions
    4. 460.67 millions
Correct Option: B

As per the given above table , we see
Difference in percent of people in the age groups (46 – 55) and (26 – 35) = 17.25 – 14.25 = 3%
Now, 3% of total Population = 11.75 million

∴ Total Population =
11.75 × 100
