  6. Directions(6-10):
    The following graph shows the percentage growth in population of six
    cities from 1990 to 2000 and 2000 to 2010.

  7. The population of City E in year 1990 was what fraction of its population in 2010?
    5/7
    10/21
    11/15
    13/17
    11/12
    Option B
    Let the population of E in 1990 be 100.
    E(2010) = 100* 150/100*140/100 = 210
    Required fraction = 100/210 = 10/21

     

  8. If the population of City C in year 2010 and that of City D in year 2000 are equal and they are 27.2 lakh each the population of City C in year 1990 is what percentage of population of City D in the same year?
    60%
    40%
    30%
    50%
    20%
    Option D
    C(2010) = 27.2 = D(2000)
    C(1990) = 27.2*100/170*100/160 = 10 lakh
    D(1990) = 27.2*100/136 = 20 lakh
    Required% = 10/20 × 100 = 50%

     

  9. The population of City D in year 2000 was what per cent of its population in year 2010?
    36.7%
    40.5%
    22.2%
    62.5%
    40.5%
    Option D
    Suppose the population in year 2000 was x.
    Its population in year 2010 x *160/100 = 8x/5
    Required % = 5x/8x*100 = 62.5%

     

  10. In year 1990 the population of City A and City B are equal and the population of City A in year 2010 is 37.7 lakh. What is the population of City B in year 2010
    45 lakh
    30 lakh
    38 lakh
    40 lakh
    42 lakh
    Option E
    A(2010) = 37.7 lakh
    A(1990) = 37.7* 100/145* 100/130 = 20 lakh
    B(1990) = A(1990) = 20 lakh
    B(2010) = 20*140/100* 150/100 = 42 lakh

     

  11. If the population of City F in year 1990 was 12 lakh, what will be its population in year 2010?
    30.05 lakh
    32.23 lakh
    32.55 lakh
    30.50 lakh
    22.44 lakh
    Option C
    P(1990) = 12 lakh
    P (2010) = 12 * (100 + 75)/100* (100 + 55)/100
