Answers
1. 2
A2013 = 540000 * 120/100 * 130/100 = 842400

2. 4
Let the population in year 2011 = 100
Population 2013 = 100 * 115/100 * 115/100 = 132.25
% increase = 32.25%

3. 4
Let the population of D & E by 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 * 100/135 = 960000

5. 3
D2013 = 600000 * 135/100 * 125/100 = 1012500

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

Diff = 1012500 - 900000 = 112500
