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
