= 5^ 4 = 625 - The population of City E in year 1990 was what fraction of its population in 2010?
5/710/2111/1513/1711/12Option B

Let the population of E in 1990 be 100.

E(2010) = 100* 150/100*140/100 = 210

Required fraction = 100/210 = 10/21 - 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% - 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% - 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 lakh30 lakh38 lakh40 lakh42 lakhOption 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 - If the population of City F in year 1990 was 12 lakh, what will be its population in year 2010?
30.05 lakh32.23 lakh32.55 lakh30.50 lakh22.44 lakhOption C

P(1990) = 12 lakh

P (2010) = 12 * (100 + 75)/100* (100 + 55)/100

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