Answer & Explanation

1. 4

A2013 = 540000 * 120/100 * 130/100 = 842400

2. 4

Let its population in 2011 = 100

Population (2013) = 100 * 115/100 * 115/100 = 132.25

%Increase = 32.25%

3. 4

Let the population of D & E are ‘X’ in year 2012

D2013 = x * 125/100 = 1.25x

E2013 = x * 145/100 = 1.45x

Req% = 1.45x/1.25x * 100 = 116%

4 .3

F2011 = 1684800 * 100/130 * 100/130 = 960000

5. 3

D2013 = 600000 * 135/100 * 125/100 = 1012500

B2013 = 600000 * 125/100 * 120/100 = 900000

Diff = 1012500 – 900000 = 112500
