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%

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
P(2010) = 12 × 1.75 × 1.55 = 32.55 lakh
